My F-I-L owns a mid-80's 300D (I think) with 205K miles. It runs and looks beautiful since he has taken great care of it. However, he is afraid that he'll start having maintenance problems because of the age/mileage and wants to upgrade to a newer model. My understanding is that '97 was the last year of diesel MB's in the USA, and a local MB mechanic suggested that these newer diesel engines are problem-ridden (maxing out at about 75K before major problems start showing up). <br> <br> Does anyone have an opinion about the last year MB made an excellent diesel engine and what body style it belongs to? Should he just keep with the current vehicle until it breaks down?
