Do not buy this car! 
 I had my engine and cat converter replaced in Aug of 07 free of charge due to only having 78,000 miles on my car. But they charged me for replacing my O2 sensors which was $450.00. Just last month in April one of my ignition coils went bad. Dealership wanted to replace all four. I declined and just got the bad one replaced. Two weeks ago my car stalled out on me when I was getting off the freeway, and I was barely able to drive it to the nearest dealer. Intake manifold and gaskets were damaged; they also recommended changing my spark plugs. Bottom line is these cars are pieces of crap, no matter how much money you invest in these cars to fix them something else is bound to go wrong.
