Being the responsible type... I'd have to say to not get rid of the car.. but.... just cut back on all the expenditures for it.

When I bought my Cobra new in 97 I was married with no kids living in a small house. I have since then divorced, gotten remarried, adopted a child, had my wife decide she wanted to be a "stay at home" Mom, had another child, and moved to a new house (not to mention a couple of new vehicles thrown in there as well).

And I've pushed the performance "bug" back for that many years... yet still had my "toy". It can be done... just need to decide on how bad you want it.
