Found a 2009 ZR1 with 3ZR package today with only 630 miles! I spoke with the original owner that traded it in at the same dealership where he bought it brand new in 2009. He is a 66 year old doctor. I have seen the pics. up close and personal and I can't find a mark on it anywhere. Naturally I will go down to see it in person just to be absolutely certain. Warranty is good until 2014 on the powertrain only. I know what everyone is thinking. 630 miles of racing down the drag strip. Well, in talking to the guy, he sure doesn't sound like someone who goes racing on weekends but a final inspection will tell for sure. My question to all is this. What is the car worth if it is exactly as presented? What would you pay for this car if you were going to negotiate a deal. The car is at the same selling GM dealership that sold it in the first place. Checked Carfax and nothing on it except showing 1 owner, no flood, no accidents and 1 oil change which is to be expected in 630 miles I guess. I value the opinions of all of the members here so please chime in with all your thoughts and ideas please. I have broad shoulders so I can take it if necessary. One last question. Does anyone know of any major problems or issues with the 2009 ZR1 vs. later ZR1 models? Should I stay away from this one?
