What fails on a Porsche Cayman at 12 years

All Porsche Cayman MOTs at 12 years, cars first used 2010–2013 (2,493 MOT tests; DVSA item counts are not split by first-use year). The most common fail items: wipers not clearing screen (1.0 per 100 MOT tests, a wear item), rigid brake pipes: excessively corroded (1.0 per 100 MOT tests) and tyre tread below 1.6 mm (1.0 per 100 MOT tests, a wear item).

Road tax for a 2013 Porsche Cayman

The Vehicle Certification Agency lists 14 petrol versions of the Porsche Cayman in its data from August 2011 to August 2013, from 180 to 262 g/km CO2 [3]. A car first registered from 1 March 2001 to 31 March 2017 is taxed by CO2 band, so that is 5 bands from I to M: from £360 to £790 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 2013 petrol car

Car tax and ULEZ for a 2013 car

A car first registered in the UK in 2013 was issued a 62 (January–February), 13 (March–August) or 63 (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. 13 plates

A 2013 car is taxed by its CO2 emissions band (A to M), shown on the V5C logbook. [2]

For the London ULEZ, a 2013 petrol usually meets Euro 4. The Euro standard of the car decides, not the year alone. [4] ULEZ checker
