Downsides of convertibles?

[Jordan325iC]

My convertible was not noticeably slower than my coupe w/ the same suspension. According to factory BMW manual, the convertible is 152lbs heaver than the coupe, so it's like having a passenger all the time, not the 400lb dead weight everyone always seems to assume. Though I'm sure there was more chassis flex, I haven't really noticed a difference on the autox course between my e30 and the old cabby.

It had all the downsides inherent to all soft-top's. More wind noise, plastic rear window that tends to fog up and more fragile roof. I loved mine though, and it got way more positive attention than my current e30.

Electric roofs can be a pain and make sure you learn to alighn them properly. As previously metioned, there will be more rattles because of cowl shake and the structure will flex more in corners.

Noise, leaks, cost of top, the rear window clouds up over time, heavier...hmmm the interior wears faster.

The squeeks and rattles drove me crazy. Stock rear shock mounts will be blown. A blast in the twisties though.

I've been thinking of buying this clean vert, I know they're heavier, but are they alot slower or would it be hard to notice? Anything else performance wise that I should know?

And exactly how much heavier are they?

Thanks!
