Drive it proudly, of course. Yes, it's a shoebox on wheels with an engine that feels like it's suffering an asthma attack, but it can also be a hell of a lot of fun.
Sign up for the SCCA, do some autocrossing, and challenge yourself. The car itself really doesn't matter, the goal is to improve yourself. Having the latest and greatest in automotive tech does not make a btter driver, skill and determination do. Take that Mitsu Precis and go attack some corners!
