1. You can try Dave Alwood, but be very patient.

Try "king-of-bling" off here, rebuilt "righthookers" 3 door for him.
2. Not sure on that one, see above...
3. Is is THAT bad?? Get some Gunk and a pressure washer and DIY.
4. For the bodywork, give "jacko" off here a PM. He's in our local group and loves his RS's. Not a bad painter either.
5. There is a place in Redcar does re-trims, but he isn't cheap! Very good quality though.
6. Marry a rich bird?
Never heard of RLR?
Best of luck mate!
