I am looking at purchasing an '03 530i 5sp that is in Manassas Park, VA. i am in Los Angeles so it is a bit difficult to check out the car personally. The dealer, Auto Advantage, seems to have a pretty good rep but I would still like to get the car checked out. AA says they do a "250 point" inspection to certify their cars but they won't tell me what those 250 points are - they say it's like their secret ingredient. Anyway, has anyone used either Carchex or Automobile Inspections? AI seems a bit on the high side but they seem to be pretty thorough. Or can anyone recommend any other service to have the car checked out? Thanks!
