Is there any mechanical or weight difference between the '08 and '09 ACR? I know the colors offered are different and the Hardcore option would acct for 40lbs if chosen. Otherwise, would the two years be identical and perform the same at the track (assuming they both had or didn't have the HC option)? Unless one is waiting for a particular color, is there ANY reason whatsoever to prefer an '09, other perhaps, than ultimate re-sale value? Thanks for the help...this will help me decide. And what is stated Gross Vehicular Weight on ACR?
