I can not even imagine why someone would want to buy a diesel M3... americans, it seems it's true that everyone want what doesn't have. I'm bored of listening diesel tractor noise everywhere here.

If you want to make a sports car it does not make sense to use a heavier, dirtier, less reliable, less revy, worse capable, worse refined and usable engine, does it? Huge turbolag, agricultural noise and totally ephemeral power for torque figures and fuel saving? Use your gearbox man and let the I6 petrol sound properly and be refined, for god sake. If you don't understand that using the car just between 1800 and 3200 rpm is not nice, it's simply that the M3 is not your car.

I also have a 6 cylinder diesel engine, but having one is not an intelligent reason for prefering it over a good petrol engine.
