Had my 280SL 11 years now. Was in a slow restoration for 9 of those years, whereas I still have a driver to drive each of those years in the spring/summer. All my restoration was during the winter months. Each year, I would select an area in the car to restore, ie. engine, interior, paint, chassis, wheels, tires, etc. The last thing I did was exhaust system. Had to decide if I was to go with the original MB system or the aftermarket SS systems. I now show this car in AACA meets, which look for originality, so you guessed it, I went with MB parts. In fact over the course of the 9 years, all my parts were MB parts. I name my SL "BCW" this stands for Booze and Cheap Women. When people ask me where has ALL my money gone, I say booze and cheap women. Little do they know. You know to this day, I have not counted up my receipts, I'm afraid to.
Anyway, just think of the restoration process as a trip thru life, with many pitfalls. Hey, but think of all the stories you can tell when the restoration is complete. I now never run out of words at a car show when someone comes up to me and asks me how difficult was it to restore.
