That's the problems I had with the cars I restored. I had a 1964 230S, only 600 were made, only 200 had the Borg Warner manual transmission which mine had. I sold it to my brother in law who swore he would restore it, or sell it back to me. That was the deal. I even knocked $1000 off the price I paid. He hasn't touched the car. After 15 years, I told him he had time enough, and all of a suddenly, he doesn't remember the deal we had. My Great Nephew, his Grandson developed Muscular Dystrophy, and he wanted to use the car to drive him around. This is a person of means. I let it go, we knew each other for so many decades, but he has matured into a very nasty old person, and I've had enough. The car sits in the open end of his Barn rotting away, 80% worse than when I did the exchange. Sad to see such a rare car disintegrate into nothing. I learned a good lesson. We come into this world with nothing and that's how we're going to leave it.
This picture looks exactly how the car, that sits languishing, slowing decaying into worthlessness could have looked, same color, all it needed was piston rings, as Mercedes had just done the top end, but the guy I purchased it from thought Mercedes was trying to rip him off when they told him the motor could be re-ringed. At worst, a 1st overbore, and new pistons. I know and have worked on many of these engines. That's why I got it so cheap. The guy didn't understand what he had. Se la vid!
