When I worked I had a company car and it was changed regularly. When I was younger after 3 years or less, my cars had already had quite a hard life and done 60,000, often at high speed for long hours in Western Europe.
I then joined a small company and my mileage dropped and taxes went up. One day the Financial Director came into my office and asked me if I'd ever thought how much my "free company petrol" was costing me per mile in tax? It was very high and I was grateful when my company changed the deal I had.
Thinking of retirement, I decided to buy a new car and keep it for ~10 years as my American friends seemed to do with their cars. I did this and any costs divided by 10 always look better. Cars seem to be so much more reliable and last longer. My old £16,000 diesel had done 150,000 miles (at ~50miles to the gallon) when I gave it to a relative, and it still passed the MOT a year later, before any service!
This reliability is of course a problem to manufacturers, who I suspect are grateful for younger people who require the latest and the greenest new cars.
In a pro-Brexit world I guess it might be better to buy a Japanese, Korean or other Asian car rather than a German car for reliability and longevity. I doubt if French or Italian cars are bought with reliability and longevity as prime factors.
As to whether electric cars are really an option is more difficult to say. I had a look at hybrids/electric cars around a year ago and the low running costs were attractive. However range is still an issue. More worrying to me was that the leading electric car models didn't seem to be that reliable, especially when one took the high cost/lowish spec into account - without the government subsidy you'd have to be very "green" to buy one. I don't think a believable 10 year cost of ownership model as been done for electric or hybrid cars. It all depends on whether the batteries have to be replaced and at what cost.
I would have thought that the drive for greener cars and ones that drive themselves would be good opportunities for world manufacturers. Post-Brexit the EU-UK tariffs might mean these opportunities will be taken in Asia and the USA, rather than in Germany or the UK. Especially as the USA-EU tariff talks seem to be at an end.
Personally I have recently been very impressed with a friends Note diesel. Quiet, ~70miles to the gallon and a nice place to be. And made in Sunderland, so no EU tax.
