Autobahn Engineering Melbourne, Florida, specializes in w113.
In fact it is the shops favorite car to work on. The owner is an ex-Factory Porsche mechanic as well. His name is Tom. Great team at his shop (factory trained Mercedes engineers) and he has done many w113s and 190SL’s including my 250SL. He cringes when someone brings in a recent model Mercedes and instead prefers working on the classics. He really puts his sweat, blood and tears into every aspect of fixing up 190's, 230's 250's and 280's. He is so knowledgeable and knows all of the major parts suppliers on a first name basis. I did hear him mention he does not care to work on the 190SLs but prefers the W113 instead. He did restore an amazing 190SL though and has full books of pics and very happy customers.
New soft top, no problem, broken softtop frame, no problem, complete frame off restore no problem, engine, body fitment, etc, etc, top notch work.
I cannot say enough good things about his service and pride in his work. The only issue is he stays busy due to his reputation, but if you say w113, he will definitely take on the project with amazing results and dedicate all his time to the classics and push off the soccer moms in their MLs and late model ,SLs, C and E Class, etc.
Best mechanic I have ever worked with and one hell of a nice guy with a pure love for the w113. BTW Body shop work is contracted out to Lanes which is a Geico repair shop normally but they have body guys who are top notch and their paint guy is very, very good. I think it is the nice Florida environment that attracts a large amount of skilled professionals who should be in LA, NY, Chicago, etc but prefer the warm winters and slower pace of a Mid-sized city near the beach.
