I purchased the vehicle used when it was a year old and 50,000 miles on it. It is one of the most reliable cars I have owed. It currently has 100,000+ miles and I have not had any major issues with it. The fuel economy is somewhat neutral at 28 mpg. The interior in 2008 was standard, but now in 2015 it is extremely outdated and starting to deteriorate. As far a engine components I have keep up on regular scheduled vehicle maintenance and have had no issues. By far if you need a reliable vehicle with no major mechanical issues then this would be a great pick.

I am displeased with the Pontiac Grand Prix in large part due to the amount of repairs that it constantly needed beyond the 35,000 mile mark. Before it hit that mark it ran about as average as a car could run, but once it hit that mile marker it became inefficient on gas consumption and mileage. I have had significant issues with the alignment of the tires on the car, and when you drive through the heat of the desert it impacts these tires greatly. I have had my oil checked consistently and without fail, the car will begin to overheat if you drive it beyond 30 minutes. It goes into the dangerous zone for overheating and it is a safety issue. The replacement parts are highly expensive, pretty much each time I take the car in it is guaranteed to cost $700+ due to the expense of the car's parts. One of the major issues is the car was discontinued after a certain point, so replacement parts became hard to come by. It has been an extremely expensive car to maintain and really does not allow for out of state travel due to the chance of over-heating.
