Hello I'm new to this forum. I purchased a 1983 300sd it has 178000. The odometerhas stopped working on it. There is no rust to be found underneath the car, all of the floorboards are intact. The car is currently in the shop to be brought back to factory specs. This is going to be my project car for now. I'm trying to make it a super sleeper. What can I do and what can the car handle.
