loaners tend to be ragged out a bit, so i wouldnt have gone with that one. as far as the one with 300 miles on it... could have been something wrong. but then agian that depends on your definition of buzz-box. you mean the engine itself got loud? or the frame was making noise? maybe it was road roar? possibly items loose in the car? the gas pedal shouldnt have been vibrating, but again, i dont know what your used to.

we get people in (i work at an acura dealership) who "feel vibrations" and some of it is just normal. other times, its an issue that we can never get to replicate.

kinda reminds me of the chick who wrecked her car and tried to get us to warranty the front bumper cuz she believed that the bumper sides shouldnt have popped off.. lol
