I get immense pleasure from driving the car even to the shops and back.
The day im there thinking "oh i better take the runaround because X is too costly to run" is the day id rather sell the car.
Ultimately its what I do for fun, I don't do nights out, dont drink, dont smoke, dont gamble etc... I have mates who go for a night out in Worcester and Birmingham every week at 100+ a pop... I don't do that as I don't derive any pleasure from it.
Soon as you reallocate those sort of costs into the car, it becomes comparable quite quickly.
Most people don't spend 1k a month on nights out though. I've been out in Birmingham on twenty quid LOL
