Sure George.
btw, the flexing on the newest 9-3 convertible body style is nearly non-existent now. They have a separate subframe (and undercarriage brace) that probably costs SAAB $1000 extra alone in manufacturing costs...but it entirely remedies flexing.
It really is a horrible problem with the older body style. If you can afford the newer body style, I'd vote for that.
I have a 2008 SAAB 9-3 AERO (wagon) and drove the convertible and found it to be remarkably similar in body solidity (the 4 door and wagons don't have the pricey sub-frame).
Note that it was a non-AERO convertible I drove (slightly softer springs and smaller, 55-series 16" wheels) whereas the AERO models have stouter suspension set up and 45-series 17" wheels so the comparo with body flexing wasn't exactly perfect.
My wife has a 2004 BMW 325ci convertible (non sport suspension) and it's good (she likes it)...but, I think the SAAB is a better value and slightly more roomy inside.
