Hello, I’m new here and I want to buy an Omega! I’ve read that the rust preservation has been greatly improved since the BJ 07/96 (i.e. already before the Facelift in 98). Now my question: Is first registration the same year of construction? Probably not! In the advertisements, however, only EZ 09/96. How do I know that the car was built after 07/96? Thank you for your help
