1968Chevrolet Corvette
The Coke-bottle 'shark' body — the longest-running Corvette generation. Big-block muscle early, then detuned through the 1970s emissions era; the original ZR1 option appeared 1970–1972.

Reliability & ownership notes
- For a 1968 Corvette, verify the VIN, installed powertrain and service history against the exact-year GM document; age, modifications and deferred maintenance are more useful evidence than generation-wide reputation.
- Check the NHTSA VIN lookup for unrepaired safety recalls before purchase or road use.
