I looked at a really nice W123 today. Only a leak on the engine makes me worry. I hung up a picture for example. Directly under the radiator hose is such a small bridge on the engine and there “stands” oil. It was still very thin liquid. Where can this come from and like “worst” is the whole. Edit. Since here many in the forum already see on pictures more than I live here the link to the car Mercedes-Benz 230 TOP STAND W 123 “230” 1977 RESTAURIERT for 8.500 € at mobile.de : https://suche.mobile.de/vehicles/details.html?id=227007388 https://suche.mobile.de/vehicles/details.html?id=227007388 I found no rust.The car was repainted in 2008.If what would have rusted I would have seen it. Is just a 230 without everything. I’m not sure if the 850€ are ok.
