Things I can live without:
Air conditioning. Heat never seems to effect me as much as it used to. I know you americans love your aircon though

Oil bath air filter. Sure it's a good system but it makes the car hella noisy and i'd rather change out a paper airfilter than spend an hour emptying and refilling the oil bath.

I can live without starting in 2nd on take off. This feature really gives me the irrates, I live in a country where it almost never snows, yet I have this feature.
