Hello all, I just bought a pristine, single owner 79' 450SL roadster for my wife. I don't know anything about MB's as I am normally used to wrenching on Chevy's. My toy is a 63' roadster Vette. I would like to do a few mods on this 450SL such as rims/tires, bumper swap and maybe exhaust. What are the usual performance enhancing mod's that are typically done on these?
