I gave up fixing the newer cars, too.
Even if I could get on my mechanics crawler, they could use it to wheel me to the ambulance. When I was a teenager, I ran a local gas station on Sundays. It had lifts, and my family car had the most lubricated ball joints and cleanest oil ever.
Fortunately(?) I have an old house, by American standards, that gives me plenty of repair work to do...
