Re: Spider roll hoops.
I know a few guys with Mercedes SL's, they would kill to have the problems you have, which are minor in comparison to the constant bodywork damage and bott full of water...and roofs that wont close.
And another who has just had his new A4 cabrio painted for the 4th time when yet again it got all uncoordinated and crushed the boot lid...
You need to put up with a bit of grief with cabriolets I am afraid - at any price, they are complex pieces of kit.
Unless you get an (fabric roof) MX5, which is one hand manual operation in a second and is great.
