No item fails at a clearly different rate from all class 4 vehicles the same age across 3 or more ages.

Car tax and ULEZ for a 2019 car

A car first registered in the UK in 2019 was issued a 68 (January–February), 19 (March–August) or 69 (September–December) plate, unless it was registered in Northern Ireland (no age identifier) or has since moved to a private plate. An imported one is plated when first registered here, so its plate can be newer than its first-use year. 19 plates

A 2019 car pays the standard rate after its first year. If its list price was over £40,000 it pays the expensive car supplement in years 2 to 6 (to 2025), which has ended. [2] Car tax calculator for a 2019 petrol car

For the London ULEZ, a 2019 petrol usually meets Euro 4. The Euro standard of the car decides, not the year alone. [3] ULEZ checker
