How about Mike Dawson, 42 Holman Road, West Ewell, Surrey, KT19 9PG. Telephone 07783 024248 or mikedawson@orange.net. Former Ducati London techie, started on his own. Just off the A3 near Tolworth. I've just booked my 996 in with him for next week. Came well recomended.
have used ducati proteam for 6 years on 900SS and 748, and mate takes his 888 there. talk to matt or alec(short) 020 8947 7555 located 59 weir rd sw19 8ug (wandsworth/wimbledon dog track area) near a tube stop too (wimbledon park) for egtting to and from without bike.
I can highly recommend Dave Robinson. He really knows his Ducatis and has looked after me and my bike(s) over the years. He always seems to have time to fit my 'emergencies' in. And the idle conversations we have when I drop the bike off or pick it up are always educational and enlightening. A real gent who has survived the comings and goings of various Ducati franchises in the area simply because IMHO he does a great job.
I haven't got experience of the others mentioned so can't offer a comparison.
