And it’s one thing if your car breaks down on a side street, it’s completely different if it breaks down on an interstate. If you have a daughter would you be comfortable with her driving an unreliable car? Your wife? Your mother?
For an anecdote, consider that Jeep just bricked thousands of new cars, including on interstates 2 weeks ago.
That GM recalled most 6.2l engines made in the last 5 years; ... Toyota engine castings, bmw chain tensioners, Ford Ecoboost coolant passages, Porsche bearings... Most of these problems became apparent before a long term first owner sold (yes, you should do research)
A pre purchase inspection, and all around maintenance (brake, coolant, oil, transmission oil, and differential oil) will get you a long way; a $2k suspension refresh will take you even further.
It sucks if you spend $3500 on a car only to spend another $2000 because the transmission went out and the timing was bad luck. I wouldn't recommend anyone buy an old car I'd they have no emergency fund left after the purchase though.
My wife does regularly drive our old cars. If it dies on the highway we'll deal with it. I don't have a daughter, but I wouldn't worry about my kid driving the kind of old cars I pick up - I'm patients picky, and able to work on them myself. The car would be the least of my worries if I had a young daughter with a drivers license.
