Does anyone know if a certificate of "conformity - Subaru Forester 1998 model" was ever produced?
If so, does anyone have a copy?
Has anyone been able to register a Subaru Forester 1998 model as ULEZ compliant?

 

They are specific to the actual vehicle. See here to get one free and easy: https://www.scoobynet.com/scoobynet-...-for-free.html

Unlikely to have it registered as compliant. if it was a 2001 then there is a chance, as the emissions data was a requirement then. Could be different is yours was an import, but you didn't mention that.
