A recent report came out indicating that US muscle car sales have been in a bit of a slump over the past six months. It's too soon to tell whether or not this is a long-term trend. But there's some good news as well. According to The Detroit Free Press and Kelley Blue Book, all three muscle cars, the Ford Mustang, Chevrolet Camaro, and Dodge Challenger, are "showing surprising (value) strength as consumers shift to SUVs (and that) a three-year-old Camaro, Challenger or Mustang retains significantly more of its value than other vehicles."

These three cars now retain 48%-49% of their value after three years. For comparison, most three-year-old vehicles of any class "hover between 40% and the high 30s." So what's the muscle car secret? More than likely it's because dealer incentives on them are usually lower than other types of cars, thus leading to higher residual values. When cars have "natural demand (they do) better as used cars." These numbers even take into account Mustang and Camaro convertible fleet cars, typically everyone's favorite vacation rental.
