April Car & Driver G37
 

The April Car & Driver reviews $50,000 convertibles, and does a number on the G37 convert. It says the car wasn't made stiff enough to accommodate the loss of roof, a problem which was solved on the 370Z roadster (which it says has the same "basic bones") with body stiffening on several body points. Infiniti is not going to like that article - its really harsh.

Stiff enough for what? Road course racing or general street driving?
I have seen a few on the street and it is hard to tell coupe v. vert unless you spot the ugly antenna.
