A $240,000 McLaren MP4-12C and a forty-year-old Chevrolet Chevelle SS 396 line up for a quarter-mile grudge match that starts as a joke and ends as a real argument about value. The Chevelle’s 13.7-second pass impressed viewers enough that the comments turned into a debate about depreciation instead of horsepower. One of these cars has held its worth. The other hasn’t. Watch which one wins where it actually counts.
