Good question, I think that it all depends on what it's worth to you.

I don't have any personal experience with them although I too have seen nice looking cars on their site. Not too long ago they offered a 1985 300TD wagon, white with palomino MB Tex interior. Supposedly there was no rust anywhere and all paperwork came with it. They wanted 11,900.00!!!!!

IMO, for that kind of money there ought to be absolutely nothing wrong with the vehicle- in fact, I think that the vehicle should have been subject to an extensive inspection and refurbishment/ minor restoration prior to sale. Records are important but at what cost? Also, just because there is no rust showing on the outside doesn't mean that it's not on the inside!
