Thanks everyone for the advice. Damn, I hoped that once I bought the car I'd be done dumping loads of cash into it.
Oh well. This is the first car that Ive actually felt was worth my time upgrading.
Well looks my first real upgrade will actually be to buy a house.
I've been saving for awhile and when I move in about a year I think it'll be time. So I'm going to just enjoy my Boxster as is for awhile, and put my money towards that goal.
However, once that's done...well the Boxster will be long overdue for some upgrades
Until then, I'll just look at pics of Perfectlap's car
