Thank you, that was really useful.The question has been asked many times before (do a forum search) but here is one thread:
2001 Z3 Sill panels
The sill panels on my 2001 1.9 Z3 are pretty rotten, i had them done a few years ago but the rust has returned as always. Have seen some GRP (fibre glass) 1s on Ebay for about £290 supplied in grey so will need spraying. This is probably a common problem. Does anybody have any thoughts on...zroadster.org
