I'll save you the trouble of searching.
Don't do it, 335i's have major issues with turbos failing, you will have to replace your fuel pump 50 times. Headlights popping loose when it run over bumps. spark plugs need adjusting every 40 miles. You have to keep spare water pumps in the trunk because to break too. CEL coming on if you accelerate too hard. Just a money pit. But put JB4+ on it and you'll be smoking M3's all day long /End Sarcasm
