You don’t have to buy a banger, just buy a new car and drive it for 20 years. You will save vast amounts of momey.
I did this and now I'm stuck with manual Kia... But I don't really drive enough to care, so I'm fine...
Everyone I know driving 100k+ 10y+ cars from reliable manufacturers have no issues beyond regular maintenance.
My father's Benz certainly spends more time in the shop though.
