This is jut to hard to get ones head around. The cheaper route, I think would be to sell your N/A and buy an SRT. That is if you are attached to the Crossfire body style.

If not, then sell your Crossfire and buy something else that has what it is you're looking for.

I can find no fault with the 320 engine, it'll pop off tall 14 second quarter miles and run much faster than you'll ever catch me driving. All this and it still gets a constant mid 21 MPG. Above all the Crossfire has character and you don't see many cars these days that have character.
