I was able to sit in a Solstice at a local dealer and play with the top. I've sat in a Kappa platform at autoshows but not been able to operate the top. I am 6'2" and I fit great with top down or up, head room and leg room!
With the top up, if I pack using soft luggage, there is no reason I shouldn't be able to get enough stuff in there for me and the W to travel for at least a week. It really is a bigger trunk than people or pictures indicate. That means, no luggage rack.
PS - This is a dealer (Mazzei Pontiac of Pittsburg, CA) that should go on the Soltice forum as a gouger - $5K over invoice. A "limited availability" mark-up, even though there were 5 Sols on the lot!
They didn't have too many options when I ordered mine. No performance suspension, no locking gas cap, no windscreen, no mud flaps, etc. Guess I will see what they look like, what after market brings out and decide what to go with. Have seen the windscreen that looks better, cheaper a couple of places, so things are coming out.
