E46 Cabrio hard top- worth it?

[Robertb]

I have an Alpina B3S Cabrio.

I do a fair few motorway miles, and sometimes find the windnoise and general racket from other vehicles quite wearing (yes the roof is closed!) so am thinking of getting a hard top for the winter months.

Do they make the car coupe-like in refinement? Do you notice the extra weight?

Any views much appreciated.

Robert.
