Bought the MP3 today! I finally understand why you guys love this car so much. The dynamics are incredible for the price. My car does seem to have an issue, though, and I was wondering if anyone else had experienced the same thing. There is a semi-loud noise coming from the rear suspension area that occurs at any speed over even minor bumps. It's kind of a low-pitched klunk. Let me know if this is common. The seller said the noise has been present since the car was new and they brought it in to be checked out, but the dealer said it was normal. I find this hard to believe, since the noise is quite loud and obtrusive. Let me know if you know anything!
