1992 Mercedes-Benz 300-Class Diesel 300D Turbodiesel 4dr Sedan
I purchased the car with 255k on it. I have driven it for 3 years now and the mileage now sits at 448k. I once read in one of the snooty Mercedes forums that "the legendary half-million mile diesel is largely urban myth." I expect to go well beyond this number. I don`t baby it either. I sometimes go up to 16k miles between oil changes and pour used vegetable oil right in blending it with diesel in summer only of course. This has had zero effect on performance. A German tank!
