What to check on a used 2020 Chevrolet Corvette
Structure (10 complaints on the 2020): look under the car for rust or damage around the subframe and rockers, open every door and the liftgate, and check panel gaps for signs of repair.
Powertrain / transmission (6 complaints on the 2020): test-drive from cold through every gear and feel for slipping, harsh or delayed shifts and shudder; ask whether the transmission fluid has been serviced.
Visibility / wipers (4 complaints on the 2020): test the wipers at every speed, the washers, defrosters and the climate system.
Engine (4 complaints on the 2020): cold-start it yourself and listen for ticking or knocking; check for oil leaks, low coolant and a lit check-engine light, and ask for oil-change records.
Electrical system (3 complaints on the 2020): test every light, window, lock, the infotainment screen and the charging system, and have the car scanned for stored fault codes.
Recalls: confirm all 4 campaigns above were completed on this VIN.
