Just been washing my new pride and joy (1989 W124 300E) and noticed a couple of rust spots. One the size of a 5p on the front corner of the passenger wing, one on the offside front wing and a rust spot the size of a 10p on the offside windscreen pillar. I took it down to my local paint shop and they quoted me £350 for getting rid of the rust and respray both wings and the pillar. Is that a good price?
