I'm in the same boat & I'm 17 too!! Man this is such a pain. Life is soooo hard some times
but we can deal!. In addition to having to trade my 330 for a new 335i, I also have to get a new pony. My old pony, "Ms. Prance-a-lot", got 'tail rust' and we had to put her down! OMG, I loved that pony! But her tail was super nasty and she was soooo stubborn. My 330 is super dirty too. Nothing big, but really messy inside, and OMG sloooow compared to the 335! Keep me posted on your travails! I have some poor friends who might be interested in your 330i... I'll email them about yours.
