Big thing the Challenger has over the Mustang and Camaro is a very useable back seat and trunk. Plus they have a back up camera available. I can hardly wait to get the AWD GT slightly used in about a year's time. I will be keeping the 2010. When I buy the GT, it will be bye bye G body, I can only keep so many cars.
Pros for G bodies:
Last Oldsmobile V8 powered 2 door rear wheel drive car made.
Turbo Buick's
Cons:
Too many to list but,
Rust
Crappy heat
Junk wiring
7.5" rear, GM never learned look at the 4th Gen Camaro
Anemic old school motors, they could have went efi across the board
Crappy transmission's
Crappy suspension, actually worse than the cars they replaced and rear frame rails that always rust first
Mediocre brakes with no performance upgrades on performance models, as said no rear disk brake option
Little value other than the GN/GNX and maybe the
Hurst/Olds
I will miss my G body but at the same time I won't
