Why is it that if you ask someone for help, your problem is solved a few hours later?
Well, ten days in fact!
When I had just started this thread I thought, well, why not try again. So I skipped a few races and at the point where the used cars change, I check it again and guess what was there, all the way down: a nice, cherry-red Toyota 2000GT '68.
Went straight into my garage: I love the looks, the feel, the drive.
Then I thought of the other rare cars I read about when I searched for info on the 2000GT.
So I check the different types and guess what: in the nissan used lot: '71 Skyline GT-R, '84 Skyline RS-X.
Then the Mazda: '83 RX-7 GT Turbo, RX-7 RS-R.
They were almost all there.
