PRIOR ACCIDENT
The 2006 Grand Prix i'm looking at has 73,000 miles and the car fax showed that it was in a prior accident.The Dealer (which has a good rep) doesnt know the extent of it but said that they put it on the lift in the shop and the frame appeared to be not compromised in any way. The car fax showed that the car was driven another 20,000 miles before being traded in...I test drove it and it was smooth and tight... I am not a pro, should i have any concerns?
