C&R recently had my valver for major work (some rewiring, full exhaust, top end rebuild, some work to the bottom end, cat 1 alarm and various other bits and bobs). All I can say is that they did an absolutely fantastic job and the car runs beautifully now. Steve was happy to chat and discuss and show me all the work that was done.
The only thing that was a little disappointing was that it took two weeks instead of one. I'd recommend these guys to anyone, although they are a little expensive (though you get what you pay for in my book!).
