Sorry to hear you have sold the M3W but good news on the trade in value. I am sure the Roadster will be more civilised and comfortable with (relatively) lots of room. I hope I can still call you with the difficult electrical problems?
Absolutely if I can help.
It was a frustrating decision but now its done feeling better about it, especially given the recent Roadster spec. changes giving five point coil sprung rear end and likely disc brakes which I will benefit from

Having said that already missing M3W style open top motoring in this fine weather. Presently musing over taking the hardtop off my Land Rover as a poor substitute

Plan to be at as many three and four wheeled gatherings as feasible so hopefully see you in the not too distant future. Will certainly be at the yet to be publicised dealer day at KH which I believe will be next month.
