As it turns out, the stereotypes happen to be true.  Expensive vehicles and fast driving cause men’s testosterone levels to spike, reveals a study from Concordia University John Molson School of Business.

The study involved 39 men who volunteered.  Each of the men was told to drive down a pedestrian loaded street, as well as a calm residential road.  They drove each of these streets twice, each in different cars.  The cars were a brand new Porsche 911 Carrera Cabriolet and a 93’ Toyota Camry.  A sample of saliva was taken by researchers after each drive in order to measure the testosterone levels of the men.

According to the results, it didn’t matter which street they were driving on, however after driving the Porsche the men always demonstrated an elevated and sustained level of testosterone.

The author claims that men use expensive and powerful cars as sort of “sexual signaling devices”, much like male peacocks do when they show their tail feathers.  One thing is for sure though, although men are busy trying to impress women with their hot cars, they still need to buy an auto warranty to protect them.

BMW already uses a start-stop engine for their non-hybrid European 1 and 3 Series, but Mazda is in the process of developing a version that is more efficient.  Mazda’s system that has been independently developed is called Smart Idle Stop System.  According to the company, this system will improve fuel-efficiency by around 10%.

The unique thing about Mazda’s system is how it restarts the powertrain.  Engine restart is initiated by employing the direct-injection system to spurt gas and ignite it under the specific conditions needed to make a downward force on the pistons that is perfect, seamlessly restarting the engine.  According to Mazda, drivers won’t feel any delay because it will only take 0.35 seconds to resume driving.

Mazda’s system appears to be a lot simpler than most other start-stop systems, which are commonly attached to hybrid systems.  Also, it will cost and weigh less than GMs mild hybrid system.  If Mazda combines this system with their new turbo, which is fuel-efficient, it could boost fuel-efficiency by about 40% in a few years, without any expensive hybrid technology.

Just remember, with any new car technology you should protect yourself by purchasing an auto warranty.  After all, you want peace of mind that you won’t have to pay unnecessary repair costs.

With the high gas prices and poor economy, drivers are feeling the pinch.  And while you don’t have control over costs, such as gas prices, maintenance, and an auto warranty, you do have the power to maintain your vehicle’s value by making it last longer.  Your choice is to buy a new vehicle every few years, or to maintain your current one.  Here are some tips to keep your old gem running great.

Perhaps the most important thing you can do for your car is to get regular oil changes and have your oil filter replaced regularly.  In addition, don’t forget about your air filter.  Changing this will allow your vehicle to breathe easier and help your engine last longer.

Don’t forget about your vehicle’s cooling system.  Keep coolant levels as recommended by your owner’s manual to avoid an engine melt down.  You wouldn’t think that a simple act such as this would save you from major repairs, but neglecting to do this will have you using your auto warranty more than you would like to.

The least expensive maintenance tip is to make sure your tires are inflated to the proper levels. However, the benefits of this are immense.  You will get better fuel-efficiency, have your tires last longer and have a safer vehicle.

Find a mechanic that you trust and use him for all of your car service.  This way he can get familiar with your car and know your car from the inside out.

If you want to avoid purchasing a new car right now, follow these service tips to keep your current car running like a champ.  And, make sure you purchase used car warranties so you don’t have unnecessary repair costs down the road.

Many people maintain their car under the hood but neglect their car’s exterior.  To freshen up your car and make it look brand new, follow these simple tips.

To care for your car’s exterior start by giving it a comprehensive washing.  You’ll want to remove all of the mud and grime that has built up on your car.

Make sure to use a pH balanced wash on your car.  You should avoid harsh detergents because they will strip off the car wax on your vehicle.

After a good car washing, make an evaluation of the surface of your vehicle.  You can do this by rubbing your hand along the surface of your vehicle.  If the surface feels rough on your hand, chances are you have bugs, tar, or water deposits.  These things need to be removed before you wax your car.

After doing these things it is time to put a car polish and wax on your car to protect it’s finish from harmful elements.

Make sure to be proactive when it comes to taking care of your car.  This includes maintenance, washing, waxing, and buying an auto warranty.

It is helpful to use a car loan calculator to determine what the cost for a new or used car purchase will be monthly.

These can be found online with options for buying or leasing.  This is a helpful tool in determining what your budget actually is and how much car you can afford.  Just remember to factor in other car costs, such as maintenance and new car warranties.

Just remember that the numbers on a vehicle loan calculator are not actual quotes.  The calculator allows you to compare the costs of different cars and see what your payments per month will be.

On the calculator there is a line to enter the dollar amount you would like to finance. Then, by clicking your mouse you can compare what payments will be, with different arrangements for paying.  You can also find out what interest payments will be for the life of the vehicle loan.

It is a bonus to use a car loan calculator before going to a dealership to buy a vehicle.  You will already know what your budget is, which will allow you to make a smart purchase.  You will also know how much money you have left over to spend on maintenance costs and an auto warranty.

It is a huge disappointment to buy a vehicle just to find out that it literally has an ocean of problems.

Unfortunately, there are a large number of vehicles on the market within the last five years that have experienced flooding, rain or hurricanes.  In fact, the number of cars has doubled.  In certain states it has been reported that there has been an increase of six times more cars damaged by water than five years ago.

Many times, cars with water damage are moved from flooding regions to areas that are less suspicious.  The cars are then back on the used car market, often disguised and rebuilt.

It can be difficult for consumers to be able to recognize if a vehicle has experienced water damage, and yet the car will literally rot inside and out.  In addition, the mechanical systems of a vehicle can be threatened or ruined without any visible signs on the exterior of the car.

Sales this year are predicted to reach around 45 million this year, so motorists should be on alert for water damage.  In addition, purchasing an auto warranty is a smart idea to protect your wallet in case of unforeseen repairs down the road.

Ideally, people like to take their time to purchase a new vehicle, but some drivers just can’t wait a month or two.  A theft, accident, or breakdown may leave you scrambling for something to drive.  Here’s a strategy to help you buy quickly, but wisely.

First, think about the car that you just had.  If you loved everything about it, you can purchase the same car.  However, most likely there were a few things about your car that weren’t ideal.  Maybe you needed more cargo space, more legroom, etc.  Let your old car problems be a guide for your new purchase.

Next, calculate what you can spend monthly on a new car.  You can go to CNNMoney.com to find calculators that help you determine what you can afford.

Now, its time to do some research.  Look at vehicles online in your price range that meets your specific criteria.  You can begin to eliminate cars that don’t have exactly what you need.  Make sure to read reviews on the cars that you like.

Finally, contact a dealership and go in and test drive the 3-4 vehicles you favored.  Even though you are looking to purchase fast, make sure to tell the dealer that you’re not going to buy that day.

Doing research will allow you to get the car that you want for the best price possible.  In addition, make sure you purchase an auto warranty to avoid unnecessary repair costs down the road.  After all, you never know when you will need repairs.

Often motorists get sticker shock or experience buyer’s remorse after buying a new car.  However, you can avoid this by considering the expenses that you will encounter in the future.

According to experts, most consumers anticipate the price of the purchase, registration and taxes.  However, many people forget to factor in the price of insurance and new car warranties.  Fortunately, by doing your homework you can get good deals on insurance and an auto warranty.

To control car costs drivers should consider these tips.  First of all, decide before you get to the dealership the amount of money that you can spend.  Also, decide on what type of car will suit your needs. It is also beneficial to get quotes from several dealers, because then you are in the position to negotiate.  Finally, check insurance and auto warranty prices on the vehicle that you want to purchase.

You don’t have to go broke purchasing a new car.  But, be smart and consider all of the costs involved.  It isn’t just the purchase price that you will be paying.

It’s obvious that car manufacturers have dragged their feet on developing fuel-efficient vehicles.  But it isn’t conspiracy theories that have slowed them down.  Americans have talked about fuel-efficiency for years, but when it came time to purchase an automobile, people didn’t really care about mpg.  They bought the vehicle that they really wanted, complete with an auto warranty to protect it.

Recently, J.D. Power and Associates did a study with 100,000 car shoppers asking drivers to rank what their buying priorities are.  Any idea where fuel economy ended up on the list?  It was eighth place.  Reliability came in 1st, and even image and performance were cited as being more important than fuel economy.  This survey comes at a time when gas prices are nearing $4 per gallon, and the war in Iraq is a daily reminder of how much we need energy independence.

Money is what talks, and car manufacturers listen.  If it were between a fuel-efficient hatchback and the giant SUV with a V8 and advanced technology, we know which way the money will go.  After all, auto manufacturers are capitalists and are happy to oblige.  Especially when you consider that they earn at least $5,000 in profit for a luxury sedan or SUV, and the small car results in a loss.

There has been a drastically changing landscape for the SUV market over the past year.  Driven by the poor economy, truck-based and full-size SUVs have declined in favor of car-based SUVs that are smaller.  MSN Autos has also experienced this trend among car searches.

The most popular SUV is the most popular, and best selling SUV in America.  Following close behind is the Toyota RAV4.

Three vehicles by Ford are also among the most popular SUVs.  The Ford Escape, as well as the Escape Hybrid follow behind the RAV4, and the Ford Edge comes in 10th place.  One prime example of how America’s taste for SUVs now differs is the difference in the lineup by Ford.  The Ford Explorer was the top selling SUV two years ago, however now the Explorer isn’t a best seller.

New Nissan SUVs, the Rogue and Murano have experienced great popularity, coming in fifth and seventh.

With the high fuel prices, and poor economy, consumers are staying away from big SUVs that guzzle gas, and instead are purchasing smaller SUVs.  In addition, motorists are trying to protect their wallets by purchasing an auto warranty.
