Moin, I have a question: I bought myself a nice 450 SL, Bj 1974. On the drive from the seller, after a short stop in a parking lot, the car did not move anymore, turned around on high tours, I immediately drove off from the highway to a parking lot. At the last meters a lot of white smoke came out of the engine room. I turned off the engine. Later I found that there was no cool liquid. ADAC. The car is now in the workshop. Can someone tell me what that could be. The seller says that it did not happen with him. Oh yes, I just drove about 40 km. Consumption according to indicator 1/4 tank, about 15 liters… isn’t that too much? Thank you for a reply
