Compare a a ‘55 Thunderbird, a ‘58 MGA and a ‘56 Corvette. All 50s sports cars, all successfully raced in the 50s, and all easily 6 figures at auction or private sale if in top condition

But the ‘Bird, having appreciated 25% in five years kicks the butt of the MG and the Vette when comparing appreciating values, as the Corvette's worth has only increased about 2.5% in the last half decade.
