The 350Z hard top didn't have a backseat either, but it had a support strut for structural bracing across where the backseat would be. Had to put stuff under or over it, was a pain.
That's why my wife fell in love with her G37s convertible. Basically a hard top 350 with a better interior and a backseat.
It wasn't as fun to drive though, there was something raw and honest about the 350. It was just a muscle car, pure and simple. The G37 tried too hard to be a luxury sports car, and lost a lot of the fun in the process.
I'm loving the little VW convertible we got. Great for cruising around slow in, and the most comfortable backseats of any convertible we've owned. Fantastic kids first car and I got it for $20us and have put about $450 total in it so far.
