Consumer Reports recently conducted a reliability survey to determine the overall value of three-year-old used cars in 2001 versus three-year-old used cars in 2002. A number of vehicles showed vast improvements in reliability and cost of ownership in newer models compared to older ones, but not every used car on the market today is a good buy.

ABC News recently highlighted the vehicles that did not make it to the top of the list and were instead categorized as "much worse than average." This means they had a higher rate of problems than the average model, but it by no means makes them unreliable or bad choices for drivers. Rather, knowing a car you want may come with a lot of mechanical problems could sway your decision or at least help you plan for the future.

The Audi Q5 wagon was included in the group, as many drivers reported problems with the cooling system, body integrity and mostly the audio system. The discontinued Chevrolet Aveo was also on the list, as its fuel and climate systems had sub-par ratings and there were many minor engine issues as well. The Aveo has been replaced by the all-new Chevy Sonic, which Chevy claims is a major upgrade from the Aveo.

Many of the vehicles in this category were luxury models, including the Cadillac STS, BMW 535i, Jaguar S-Type and Mercedes-Benz GL Class.The GL was found to have issues with the suspension and fuel system that could render the car completely useless.
