Adrian Flux works for me in London (Richmond). I'm 30, 1 years NCB with CSLs on the M at no extra cost -just over 600 quid so only about 70 quid over the cost of my old Audi. Not mega cheap but lower than expected for a group 20 vehicle and I only have limited NCB as I've been a named driver for years. They don't seemed fussed about mods, neither proposed spring changes or a strut brace were a concern for them.
