I can highly recomend Midway garage and bodywork in Witchford near Ely, Cambs. They restored my wifes 350 sl and did a fantastic job, they do a lot of mercs for a local indy, and have a very good valeting service. You can get your car painted, serviced and cleaned under one roof. The guys who work there are all car enthusiasts as well, involved in motor racing and the bodyshop bloke ownes an old merc.
