Pre-MOT Inspection Checklist for Porsche 911 Speedster Owners
These checks follow this Porsche 911 Speedster's own most-recorded failure strings, starting with what a tester is most likely to flag on a Porsche 911 Speedster.
-
the windscreen — “windscreen damaged”
Check the driver’s side of the screen within the swept area for chips and cracks; anything larger than 10mm in the driver’s central view is a fail. Most chips can be resin-repaired for far less than a new screen.
-
the number plates — “registration plates missing”
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.
Derived from the DVSA failure strings testers recorded for the Porsche 911 Speedster. A check that finds nothing means the item is likely fine, not that the test is guaranteed.
