Road tax for a 2005 Lexus GS

The Vehicle Certification Agency lists 3 petrol and hybrid versions of the Lexus GS in its data from May 2005 to May 2006, from 186 to 269 g/km CO2 [3]. A car first registered from 1 March 2001 to 31 March 2017 is taxed by CO2 band, so that is bands J and K: from £410 to £445 a year at the 2026/27 rates [2].

Versions listed, not cars sold: this does not say how common each band is. The CO2 figure on the car's V5C log book decides its band. Car tax calculator for a 2005 car

Car tax and ULEZ for a 2005 car

A car first registered in the UK in 2005 was issued a 54 (January–February), 05 (March–August) or 55 (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. 05 plates

A 2005 car is taxed by its CO2 emissions band (A to M), shown on the V5C logbook. [2]

For the London ULEZ, a 2005 petrol may or may not meet Euro 4, and a 2005 diesel usually does not meet Euro 6. The Euro standard of the car decides, not the year alone. Hybrids follow the rule for their petrol or diesel engine. [4] ULEZ checker
