 I got this car in May 2004.  It's a great, fun car to drive but I have several minor problems but the most important one is, while driving between 900-1100 rpm or when i go down gear, I hear a vibration.  it sounds like coming from the muffler but it doesnt.  Went back to the dealer twice and finally second time, they said that it's coming from the drive chain. Maybe they will have to take the engine out to fix it.
