Thing is when all is said and done, people expect to lose money on cars. They are a consumable, buy it, use it, throw it away.
Aaah. I don't know where to start with you on this... You couldn't be more wrong.
Only by those that can't or won't do their own repairs and maintenance. Yes they cost but by no means the level your talking.
The older the car the less you loose on it in depreciation and mark up on buying and selling. Other side of the coin is it goes wrong more often. That's where oof comes in. And my spanners.
So...
Buy and sell privately, saving of £1000 over a car dealer straight away.
Keep it ling term so save another £1000 each time you don't replace it.
Do your own maintenance and repairs at trade prices. Say 1/3 off in tc, more on used parts obviously.
No labour costs.
So the only costs are;
The car
Fuel
Parts
Minimal depreciation, but I'll break the car when I've done with it anyway, if needed.
No mark up on buying and selling.
