My personal opinion of the Sprinters is kinda mixed. The are somewhat underpowered/undertorqued for the potential weight they carry. If you are using it for a service truck its probably OK. Had an '05 come through that a professional musician was using to haul all his gear (lots of weight in amps and speakers, believe it or not). The crankshaft was literally snapped in the middle. We put a used engine in and he went his merry way. I believe he had under 200K on the clock when the engine went out, IIRC.
