19K is a very fair deal for that SRT6. You will LOVE it! Definitely plan on the Needswings DCAI. Just to be able to hear the "whine" of the supercharger at work makes that mod worthwhile. Eventually you should do the Needswings pulley saver kit as that idler pulley next to the supercharger pulley will go bad prematurely (it simply spins too fast and wears out the bearing). The stock supercharger pulley bearing will also start to go bad about that same tieme but that's an easy fix (about $60 to buy and install a new bearing pressed into the stock pulley). Personally, I decided not to spend the bucks (around $700+) for the performance gain of a smaller supercharger pulley. Then you have to start worrying about a better belt wrap around the pulley to prevent belt slippage . . . you'll NEED to get a tune and it just kind of creates new problems IMHO. Others with actual experience having installed a smaller supercharger pulley may disagree on the benefits vs aggravation & cost and maybe they will chime in . . . You will also need to change out the intercooler pump (the stock Bosch pump will fail prematurely). Also consider doing a coolant separation modification. I did the separate resevoir "spit tank" mod.

Anyway, I feel you just bought a brand new $50,000 car for $19,000! Enjoy it. I would have bought that one myself but instead of doing my usual instant gratification impulse buy, I actually thought ahead a bit and realized that I don't need two SRT6s and the cost of a divorce would have made that purchase VERY impractical for me.
