On colors--I'm a little disappointed by the various options; none of them really jump out and grab me. That metallic green is interesting but not my cup of meat. Poking around I found Gentian blue with gold wheels and that's kind of cool...but I think it's probably too much in real life.

Carmine red on the computer is a nicer red than Guards red, but is it worth the extra cost? On Rennbow it actually looks very similar.

I'd love to get green or orange but as much as these might work on a GT car I think they're a little over the top here.
EDIT: Oh, and the standard seats are manual--at least for up/down and fore/aft. The backrest is electric. Seems like the same setup I have on my car now.
