I am condidering buying a 250S 1966 - body in great shape, a few cosmetic things to do, previous owners UNKNOWN, seller states if he was to do any work on it the exhaust system should be worked on......the transmission shifts fine but seems a little hard on the gearing up....no slipping just a hard change....the driver said that the oil should be changed every 2x of gas being put in......also vehicle seems to like 60-70 mph....not more is there anything here that seems unusual or stay away from or could it be fine? Dont know a MB tech in the area of Walnut Creek Ca to go out and check??

Thanks, Volf
