Kev... carfax.com is kinda not so hot... I ran my vin for the Blazer and it came back saying it had flood damage. This however was during the time I have owned it... I think I would have recalled having my truck being in a flood! I also ran my grandparents old mercury which has a salvage title and said it had a clean title... I'm sure it can work and does work for some folks, but those two things kinda made me wonder how trust worthy their check really is...
