a bit different story, but I bought wheels for my e63 i had earlier by sending a pm to a member who was not selling them at that time. A week after i saw the ad for sale. i think I was the first one at his door!

Some one also left a note under windscreen wiper saying where I got my wheels from with his number. I texted him back. Another story, someone was asking me at NCT center about paint code (had impreza at that time).

So all you need is to give it a go. Owner will think about it and you might be lucky!
