C class Benz
I agree with jetforeman's description on the smaller engined C class. Mine is a C180, also a 4 banger and it does have this loud so-called agricultural sound like a tractor or something like that. Doesn't at all sound like a luxury car. The 6 bangers are better sounding and smoother. Mine is totally under powered, but since I have it, I will bear with this until I find a better car.
