ive only ever seen a handful of the electric roof ones and the control modules on them can work into the thousands if you've to do both
I have had people come in with the manual ones from time to time looking for bits like trims that go between where the rear seat would be and the roof comes down and there about Eur150 a piece
get people looking to replace parts of the rail and there anywhere from 100-300
fabric is no longer available for them aswell
also if anyone has a hardtop for one hold onto it cause there worth a small fortune at the minute
