I didn't buy my Z for pure speed... if I wanted that I'd get a Z28 and spend $2k on it and run 11's... I bought my Z because I wanted a Z. A car that outclasses 98% of the cars on the road, handles great, looks amazing, and is quick. 1/4 mile times aren't that important to me... But with a TT I think you get the best of both worlds. Who says Z's are slow anyway? Since when is mid 12's with basic mods slow? And 11's, 10's with more extensive work? You get all the above qualities, plus ALOT of speed.
