What fails on a Tesla Model X at 8 years
All Tesla Model X MOTs at 8 years, cars first used 2017 (2,099 MOT tests; DVSA item counts are not split by first-use year).

Car tax and ULEZ for a 2017 car
A car first registered in the UK in 2017 was issued a 66 (January–February), 17 (March–August) or 67 (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. 17 plates
A 2017 car is taxed by CO2 band if first registered before 1 April 2017, otherwise at the standard rate after the first year. Electric cars have paid vehicle tax since 1 April 2025; the expensive car supplement does not apply to electric cars registered before that date. [2] Car tax calculator for a 2017 electric car
