1969 Chevrolet Camaro ZL1

Fittingly, Chevy only produced 69 examples of the 1969 Camaro ZL1, so when one turns up for auction, it hammers for staggering sums. (One recently sold for north of $1 million, per Hagerty.)

With powerful but sleek lines and dog-dish hubcaps, this was the fastest production car to emerge from the Bowtie brand, with some Camaro ZL1s setting low 11s in the quarter-mile. It was also woefully underrated; official specs noted the ZL1 was 430 hp, but dyno tests revealed it was actually 525 hp.
