Not trying to derail this thread but, since I saw the Challenger thrown around a few times in this thread,
Last October I bought my first Mopar (Besides a 2008 JK Jeep which I also have) after about 30 years of non-stop Mustang ownership in about every conceivable performance model. I still have two Mustangs (One SN-95 GT Vert and One 84 Fox 5.0 20th Anny Car).
I traded in my seldom used 03 Mach 1 (9,000 miles after 7 years) on a 2010 R/T Classic, Super Track Pack, 6-Speed Challenger and couldn't be happier.
I thought about a GT-500 a few times, thought about holding out for a Boss but the S-197 just doesn't do it for me. Nothing against the car, I even set up my Daughter for a S-197 Convert (her 3rd Mustang).
As far as I am concerned, the Challenger and Mustang are not the same class of car. Challenger is more "personal luxury performance coupe" than Pony Car. People seem to compare the two on an apples to apples comparison when the cars are not really the same class. It more follows what the Chevelle-T-Bird style was.
I am actually sad I only got about two months of driving on the Challenger before putting it away for the winter. It by far is the best road trip car I have ever had, unlike most Mustangs you don't need a visit to a chiropractor after 3 states of driving.
Handling and ride is excellent, I like the IRS and you would be very surprised on what an STP equipped car can do in that department. Sure it's gonna trail a new Coyote powered S-197 with Ford's track pack around Watkins Glen or Summit Point but, not as much as one might think. Everybody rags on it's 4K curb weight, realistically B.F.D! You don't notice it's weight and with the amount of crap people carry around anyway. Granted jumping into my 84 2600lb Fox putting down about 270hp from the almost 400hp in 4K lb Challenger is a night and day difference in driving styles!
Straight line performance is wonderful but, it will lose again to a new Coyote S-197. As far as it being a mid-12's car, not going to happen. Realistically very low 13's, you can achieve mid 12's with an auto much easier than with a 6 speed car but I don't do slushboxes. Even at best, I would wring 12.8's out of that SN-95 DOHC Mach 1 and I was running 4:10's, Drag Radials, 31 Spline shafts and a Auburn Pro locker. Plus, that was an aggressive launch slightly slipping the clutch under track conditions. Street Light to Street Light, the nod goes to the Challenger. It will sit in low 13's with zero drama unlike the majority of most 4.6 DOHC cars. Sorry to the Ford faithful but, the 5.7 VVT is way more usable throughout the entire spectrum than the SOHC and 3-valve 4.6 cars. My Daily Drive is a 2010 4.6 Grand Marquis and I still own a 4.6 SOHC GT Convert, I'll take the "Hemi" (even though they aren't true hemi's anymore) over the 2 valve Modular any day.
I chose the 'Classic" R/T with the Super Track Pack over the SRT-8 for my own reasons and at the end of the day, with this Challenger optioned the way I wanted it actually came in more than I could have taken an SRT-8 home for. A car length here or there isn't my main consideration anymore, the only real "downside" is not being able to get the Brembo's on the "Classic" (performance pads for the STP package, otherwise the normal R/T calipers) since they only come with the SRT (the PBR's on the Mach1 were awesome)
I am really really happy with this car, the only thing (and it's a long shot) would to be get rid of this one later in 2011 or early 2012 for the new 392 SRT Challenger. That motor is a quantum leap compared to the older 6.1
I don't know if anyone saw this but, after Sema Dodge took the stock "show" 392's out to Infineon just to run. Scary Impressive for this stock 6 speed
