Buying an aftermarket auto warranty is not as happy-go-lucky as some people make it sound.  You need to pay careful attention to certain facts about the service contract when shopping around so that you do not end up with a service contract that would only serve to embezzle your hard earned money from your bank accounts.

The first thing you need to determine is the length of validity on the prospective aftermarket auto warranty (also consider the mileage features).  If the warranty covers the same period or mileage as your existing warranty, then look again – this is not the one you want. 

Secondly, an aftermarket auto warranty should provide you with coverage that your existing warranty does not have – it definitely does not make sense to spend more money for the same coverage that you already have; it absolutely does not help.

Finally, make sure that the aftermarket auto warranty that you are interested in is backed by a financially sound party, and ensure also that former claims made against this party have been paid in full and on a timely manner to those it may concern.  You would not want to buy a warranty from a party that does not pay.
