I think that the HUGE wheels will get dated. 17-19 is one thing. 24's is another thing! Also I would agree that the motors going in the cars will get outdated. An LS1 will be ancient in 10 years, and maybe it will be an LS50 or something by then!
Of course what will they think 20 years from now when they find cars with these "lateral-g.net" stickers all over them!!!
