The interior group on my '09 included pedal covers, sill plates, "Challenger"-monogrammed floor mats, and a car cover that fits loosely and is not water-proof. The interior stuff is OK, the cover isn't. All for (I believe) $750. Do what you like, but if I had ordered the package instead of being stuck with it as a result of the dealer ordering it, I would feel even worse about it than I already do. In a "do-over", I'd just piece the interior stuff together from Mopar and forget the crummy cover...
I don't know anything about a separate-option Track Pack. My car is a 6-speed and so came with the Track Pack. It's on the Monroney, but not priced out separately...
