I did think about this thread the other day as I've gone back to bangernomics.
Still got the nice cars, but I wound up with an inherited low-mileage Golf diesel I couldn't sell so I fixed it (injectors, timing belt etc) and added to the fleet.
This year has cost me many thousands in tyres (wear, punctures) repairs, warranties, tax, insurance with the nice cars, that having a shitbox you don't have to:
stare down at the road to slalom around potholes
park as far away from door dingers as possible
avoid even a tiny kerb for fear of trashing an alloy/low-profile tyre
.. is actually quite liberating.
When the entire tax+insurance of the Golf is less than one tyre for the other cars, it's worth it for all the round-the-doors I have to do with kids and care homes. Fuel/electricity is the least of the outgoings.
Not much fun though, but I've realised lots of driving around town on crap roads is never fun in any car.
