Yeah, its happening all the time.
I went to buy my E21 in May. I bought it on Ebay. Pictures were flawless ad description said flawless inside and out. I called the guy, I asked if there was even a tiny thing wrong with it. He said no. Its all perfect. I asked, is the interior black or blue, your camara is a bit dark. He said that they were black, he didnt think they even sold blue interiors....
So, I travel 10hr, 700 miles and find a car that cant even run, over heats going less than 2 miles, seat brackets broken amonst many other things, BLUE interior. Car was a wreck!
I think people know what they have, I think they just want the sale. Its just a shame they cant be honest about it. I guess you cant sell crap if youre honest though?
