Hey folks - I really know nothing about mercedes, but a family friend is selling a 1982 300sd Turbo Diesel that seems incredible, but to protect us both I'd like to get it checked out before buying.

Right now, my plan is to go to Baldwin's German Auto Werks, where the car has been serviced for many years (owner has all service records for life of car). Does anyone have any input on this shop, or perhaps a recommendation of another one?

Thanks for helping out this newbie in any way you can.
