Living with it

Reliability & ownership notes

  • For a 1981 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.
