CC Spyder ... Chassis not very rigid?

So yes, it has more cowl shake than an M3, 911 (997) drop top, and SL convertible? How much more?

The thing is.. I love convertibles, and I live in LA...Ya gotta have a spyder when it's sunny 300 days a week..

So any comparisons to any other cars?

Right..

However, does anyone have comparisons of cowl shake to other vehicles??
Does the whole car rattle or the front windshield shake when going over rougher roads?

Haha.. I've had TWO SL55's.. and I LOVE them, the 520lbs of torque at ~2000RPM is just amazing, and the car's active handling system does pretty well for a 4000+ lb car.. However, I am starting to get a little bored and want something a little lighter and sportier.. My two concerns are quality (will the car be in the shop all the time?). and whether the chassis will shake, rattle, and roll over bumpy roads (makes the car feel cheap as if the chassis wasn't solid).. On the SL because it's a convertible and a hardtop coupe the car is exceptionally solid... However, so are other soft-top convertibles like the 911 and the Boxster.. I'm just wondering if the Maser Spyder will be solid like that..
