When some people think of pre-owned vehicles, they visualize dirty, old, junky cars.  But there is another market, certified pre-owned cars, which are making savvy buyers take notice.

Certified pre-owned vehicles have had thorough inspections and refurbishing.  This eliminates the concern about reliability that often goes along with purchasing a used car.  Also, certified pre-owned cars are backed by an extended auto warranty. These benefits are hard to pass up.  Automakers understand that they shouldn’t ignore the popularity of the certified car market.

A recent study revealed that since 2000, certified pre-owned sales have risen 46%.  In fact, approximately 1.5 million of these cars are sold every year.  That is the equivalent to around 10% of new car sales.

How do you know the best and worst certified pre-owned vehicles to buy?  Forbes.com has a list that will assist motorists in making a good purchase.

The Honda Accord and Toyota 4Runner come in at the top of the list.  Next, is the Acura TL, followed by the Subaru Impreza.  The Lexus GS also comes in high on the list.

The worst cars on the list are the Saturn Relay, and Jeep Grand Cherokee.  Also making the worst list are the Pontiac G6, Volkswagen New Beetle, and Mercedes Benz E Class.

Certified pre-owned vehicles offer an updated car without the updated price.  Also key is that they come with an auto warranty.
