We bought the Blacktop charger with the 3.6, but...
it has the 8speed auto, which works great. Quick enough in sport mode (about 6.0 sec 0-60) and 30 mpg at 75 mph on the road. More like 32 if you can keep it under 70mph, but I cant.
We got the charger with leather, nav, etc for about $27k, so you should be able to buy for well under $30k.
Good luck whatever you decide.
