As you cruise car shows in the greater Los Angeles area, you might notice that muscle cars from the 1970s are increasing in popularity. Phil Skinner, editor of Kelley Blue Book’s "Early Model Values Guide," agrees. He's the sort who would rather spend time snooping around at auction yards and surfing Ebay Motors than sipping pina coladas in Malibu.

Knowing his penchant for a good classic-car deal, we asked him to share his knowledge and his photos of this latest upstart classic category. The result is this list of 1970s muscle cars that a) are still financially viable, and b) have the potential of increasing in value.

1977-78 Pontiac Trans Am coupe

Buy a Trans Am like the one in "Cannonball Run" and you too could end up with Sally Field (or Burt Reynolds) next to you as you tear up the highway. Actually, at the time, this was one of the best and fastest rides out there. Pay close attention to the engine; the 6.6L V8 was a heady performer, and today sharp examples can be found at a reasonable price. Current KBB Early Model Value, in good to excellent condition: $12,200 to $21,900. (Photo by Phil Skinner)
