Toronto MB stuff
OK, the only semi-local place for wrecked MB's is Autokraft In Waterloo. Howard is the guy, and although I have never bought anything from him, I hear mixed reviews. Autokraft's number is 519-746-2277.
As for a mechanic, I use Paul at Euromotion on 30th line in Etobicoke. He was reccomended to me by the local MB owner's club and has done a major restoration of a friends SL and quite a bit of work on my 380 SE. He mainly does older MB's and can save you a fair bit of $$ over any dealer. Very thorough. He can be reached at 416-251-4788. Leave a msg, the guy is quite busy.
Good luck with it.
