My original 2007 300C SRT-8 was pretty good out of the box for a 4 door sedan. Brembo brakes did their job and the 6.1L was able to run 0-60 in 4.7. Steering was good for the first 24K miles and would grip smooth pavement like no tomorrow. Then the front end became loose, bump steer was bad, and both lower pistons in the 4 piston front calipers seized, throw on some good old engine management gremlins and a chasis that would twist with the wind on a rough road to finish it off. Glad I got rid of mine before the new one was revealed.
But dollar for dollar, performance wise nothing with 4 doors will touch a new one, especially in a straight line. If they made the bottom end a little stronger on the new motor, the forced induction crowd will have a field day.....
