A decent vehicle report should give you the $ amount of the damage so you can eval if the accident was anything to worry about, I just got a 2004 545 with similar issue the accident was a surprise to me as well but after realizing it was only a small fenderbender of 8K which is really neglible since it happend in 2005..........
