@Hossenfeffer vehicle purchase decisions involved would be an earlier buying of a less old car, or not a LandRover Defender, Aston Martin DB5, old Diesel etc.
Petrol newer than 16 years old, diesel newer than 5y, generally.
Not, generally, of ordering a new VW ID.3 (I drove into the dealer, said "I'd like that one" drove it home, but if I'd made a specification it would have taken much of a year to arrive.

But if I had, I'd have an order form, and IIUC, would have been exempt from ULEZ charge!
