I was offerred a replica PU body kit unpainted for 5.5K.
I paid a deposit for the fabrication of a GRP body kit at one of the loacl shops. But after I saw what they put the car thru and the eventual damage after a short period of use, I gave up and forfeited the deposit.
Remember you still need fogs, side mouldings and to top it all off, M5 side mirrors, M5 alloys, air intake and maybe exhaust tips.
