Pre-MOT Inspection Checklist for Chevrolet Corvette Owners

These checks follow this Chevrolet Corvette's own most-recorded failure strings, starting with what a tester is most likely to flag on a Chevrolet Corvette.

• the exhaust and emissions — “catalyst emissions Lambda reading after 2nd fast idle outside specified limits”

  Listen for a blow at idle and have someone rev it gently. Then look at the tailpipe smoke: blue is oil, white when warm is coolant, black is over-fuelling. Any of those and the emissions test is the least of it.

• the number plates — “registration plates does not conform to the specified requirements”

  Check both plates are present, legible and correctly spaced, with the postcode of the supplier and the BS AU 145e mark. A private plate in the wrong style is a fail before the car is even looked at.

• the lights — “rear fog lamp not working”

  Switch everything on and walk round the car: both headlamps on dip and main, every indicator, both brake lights, reverse, fog and the two number-plate lamps. A bulb is a few pounds and a five-minute job.
