Royal Muscle

As the American muscle car era approached peak muscularity in the last years of the 1960s, Detroit's Big 3 all produced machinery that would stand the test of time in terms of outright performance, attractive styling, and overall badassery. These 10 cars epitomize all that was great about that period, and as a result, they're as difficult to catch on the auction block as they were (and still are) on the track.
