Looks pretty on the outside, but the "tan" leather looks Pink! and the mats have faded green. Reserve not met and and I am guessing he'd want more than 20. I check EBay Germany with a European Union search from time to time and I have never seen an E24 M6 at less than 20,000 Euro.

The tan seats are probably sun-faded Lama seats (same as mine, but they go pink-ish if the sun gets to them).

A really nice M635 can be worth over $20K, especially if in a nice shape...
