@ mercenary for hire, I agree totally with you there. If cars are maintained and cleaned and polished properly they will last for decades, my old taxi is an example 2003 Citroen C5 2ltr hdi it has 642,000 miles on it, the paint work is glossy everything works inside and out, I put a towbar on it and I use it a couple of times a week. My current taxi a C5 estate is flawless and it will kill me to sell it when its 10 years old its a pure waste and its only money making for government and dealerships. When you put a age limit on a taxi there is minimal effort to maintain or care for the taxi in its final 12 or 10 months, by keeping it open ended the inspection could be more strict any grubbiness or anything broken it doesn't get relicensed so it puts more effort into keeping taxi up to spec which is not hard.
