What about a replica that is registered based on the year it is made e.g. 1993? What base line do they use for e-testing that car? In other words, against what year/car do they e-test a Porsche replica?
In Ontario any car newer than 20 years old must be e-tested every two years, and your car is tested based on the year your car was new. A 1995 Volvo would be tested against data for a 1995 Volvo, etc.
