When I bought my car I had the choice between black 4-door GTP and red 2-door GT. Knowing what I know now, (which isnt much compared to some people on here) I would have gone w/ the GT.
With a few easy mods, you can get ur HP close to the GTP anyway, and you also always have the option of top-swap which puts out more power than stock L67 due to higher comp ratio. Am I right guys?
