Well the SRT-6 motor is essentially a slightly de-tuned AMG engine and no AMG engine comes in manual, not sure why but that's MB.

There are ways of doing it but with the amount of money you're going to put into it, it's easier to just get an SRT-6 and live with the auto. It does come with an AutoStick so you can shift if you please but it's not the traditional clutch which I enjoy.

I do feel your pain on the AM sector being slim-to-none but I don't need to go fast to enjoy the ride. Go test drive the Limited and it feels like it has more than 215 hp underneath that hood, you might be satisfied with it (it's definitely no slouch).
