I'm in a very similar situation myself also 19. Had the X for over a year and put in a lot of time and work into it. It has cost me more than it worth. All belts and pulleys, water pump, heated ccv, k&n, oil filter gasket, new brakes, tires, ball joints, tension struts, elbow intake....etc
3.0 get 14 mpg and thats if i drive it like a granny.
decided to sell it... very hard to find a buyer right now in the summer time.
I'm already loosing money if I sell it, but atleast I wont need to worry about the transmission if it starts causing problems after, almost 100k and the cluster has dead pixels...

e30 is hard to find in my area... how's e36 or e39 in terms of reliability?
