In years past, used cars may have been painted as less reliable than their brand new counterparts. While that may have been the case decades ago, it is no longer true, experts say, and buying a used car may actually be the better choice than going new.

To find out just how much the quality of used cars has improved, analysts at Consumer Reports looked at the number problem-free three-year old models in its 2002 surveys compared to its 2011 surveys. In looking at the two batches of data, they found that nearly all automakers improved their reliability in 2011, with brands like Volvo, Volkswagen, Ford and GM making the biggest gains.

Though the reliability of used cars has improved dramatically over the last several years, that does not mean you should take your foot off the pedal when it comes to doing your due diligence. Consumer Reports says there are a number of things you can do to ensure you're driving away with a good ride.

Perhaps most importantly, you'll want to be on the lookout for signs of any collision damage. There are obvious indicators, including mismatched doors and body handles, but you should also keep an eye out for trunks that don't close properly. Similarly, mold or mildew along with a discolored carpet is indicative of flood damage.

Along with its repair history you should pay close attention to what's coming out of the car's exhaust pipe. Both blue smoke and billowing white smoke are signs the engine is not working properly and would likely need a significant repair to fix.

Though being a discerning shopper is important, you likely will not have to worry about such things at New Jersey State Auto Auction. All of the dealers makes and models are CARFAX certified, so you know you're getting a reliable car no matter what.
