Nothing really just when you eject the CD it doesn't come out properly, by that I mean only a portion of it comes out, but it rarely happens so its not really a big problem.
I love this car, it has great mileage and the engine is very peppy for a 4 cylinder car, its mostly quite, but when you accelerate it makes noise (which I love, the driver seat is kinda uncomfortable, but other than that I LOVE IT.
I now had this car for a whole year, and it's still very reliable, it's only been in the shop because the track in a window broke, and something with the wiring, and that's it, both problems costing less than 200 dollars, NO ENGINE OR TRANSMISSION problems, and it's also very economical.
