Nothing, I just got the car, although the battery was dead when I went to test drive it.
I find that you need to know how to drive before you buy this car. It is hard to see out the rear side windows like you are suppose to when switching lanes. It is also difficult to see out the back if you have a rear spoiler. So all the people who think you can drive, this car really will test you.
The car has the power when you need it, when passing at higher speeds especially. You won't beat some other cars in its class off the line, but you will look better driving around town.
The 6 speed gear box takes a bit of getting used to.
I got an excellent car at an excellent price.
I recently went car shopping and I ran into several cars that had dead batteries. It is just from sittiing for a while. Sounds like you got a good car tho
