I'm thinking about buying a ML320 Benz '99-'01. I do see a few on ebay but will probably rely more on cars.com or autotrader.com. I have purchased smaller items,$100-$200 range but a car would be a major investment. Does anyone have any positive or negative experiences from buying vehicles online, preferably ebay. I am from the Southern Louisiana area, currently planning on taking a trip to the dallas/houston areas to check out some vehicles on cars.com/autotrader.com. Also, what about 3rd party car inspection company experiences.
