If you go and look at one in person you will realize you don't want one. The quality is no where near the same as the Cayman ... or the Z4 for that matter. They can advertise what they want, but I wouldn't believe them.
My biggest problem with the Solstice is that it is cramped. The trunk isn't big enough to fit more than a sweater. If you want to carry more than that your SOL or you have to get a trailer hitch.
Go look at one and make up your own mind, this is just my $0.02!
