No comparison, get the SRT.

The ONLY area that the S2K would have upper-hand is in the aftermarket. Ironically, it would take all of said aftermarket to make it as fast as bmorgan's car.

And then there's the pesky fact that, in order for a car to have huge aftermarket, there must be many thousands of cars to offset the demand.

FWIW, there were less than three thousand SRTs ever made.

It's rarer, faster, sexier, and higher quality both inside and out.
