I think it may be an issue when someone with a budget of £25-30k is in the market, same with ISF. The cars get cheaper and cheaper to buy, making them r accessible for people with a tighter monthly income. My car is an 18 plate so will benefit from cheaper tax in a year or so, might be good for 2nd hand prices, might not. It is orange after all!!
You can buy a Golf for the same price as and RCF, doesn’t mean you should. I was always told, if you can’t afford to run it new, you are probably going to struggle used! It’s why I didn’t buy an Aston Martin, and got a Lexus instead.
