The end of the road may be near for GM's rear-wheel-drive Camaro and Pontiac Firebird muscle cars.
Despite a 320-hp version of the Chevrolet Corvette's 5.7-liter V8 and available convertible models, they're among GM's slowest sellers.
Both are too bulky to be nimble.
They also ride uncomfortably.
Traction control is a worthwhile option, especially in V8-powered models.
