I've just had a late-summer build offered to me. Until I got it I hadn't really considered buying a 430 at all. So, I'm in the odd spot of having to decide whether to take it, and if so what transmission, within a couple days, but haven't had time to really trawl the archives or find colleagues with the right cars to test-passenger. 1) Anyone driven both the GT-R and the current 430 F1 and have any practical comparison of trannies? Esp. parallel parking, commuting speed, track day? 2) Anyone driven both the F430 Spider and the 90's "sportroof" Supra? My old Supra would do a little shudder when the roof was off and it didn't like the road. Evo Magazine reported something that sounded similar in the 430 Spider. Its not a deal-breaker, but I'm just curious what I'd be getting into.
