dude. nyc car.
hope your dad lets you drive it. convince him that a chip and software will improve his fuel economy and throttle response and basically everything else.
also, dont worry bout the dirt. the guys here dont care much if theres a lil dirt on the car in the showroom. this is not the detailing section.
consider dirt on a 335i like chicks mud wrestling. you know that theyre dirty, but youd still hit that every time.
just take the pics and post them.
id rather have a dirty 335 than a clean 318 anyday.
