Many people drive older cars worth less than £4000.

Sticking to old/cheap cars seems like an increasingly good option with so many scare stories about the pain and extreme expense of getting modern cars, particularly EVs, repaired.

And the impending ban on new ICE vehicles seems likely to lead to more older cars being kept on the road for a lot longer.

Yeah - a car hits a similar valuation around ~15 years of age, meaning a failure of this component limits the financially viable lifespan of a car to this amount - mechanics do engine rebuilds for less money.

My current car is my last. It's a 1997 and it runs pretty much as good as new and I expect the thing to outlive me.
