Used Pontiac Grand Prix GT (7K) +
Cartuning Turbo Kit w/ Intercooler (+4k) +
built ZZP Race Trans w/ high-stall converter and C-Ya Racing LSD ($3700) + pair of slicks ($300) ====> $15k for 11's daily driven in a 4 door Sedan that can seat 5 adults comfortably with a trunk cargo capacity large enough to hold the slicks side by side

.
In fact I've got two of my chrome wheels w/ tires laying side by side in my trunk right now

There's always a bigger fish. A nicely modified used 5.0 would beat, bang for buck, most any car these days. Question is what do you got, how much you gonna put into it, and when is it time to stop and change rides

For me 12's the limit on my car before I go RWD V8. It's "getting there" that counts, after all, because of what you learn and the fun (and pain) you have doing it...
Nice dyno man,
