Living with it

Reliability & ownership notes

For a 1985 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.
