Cars are the biggest waste of cash and I've always grown up doing my own repairs. Funny that, being poor forces you to learn many skills. My car which is a Holden Commodore Sports Wagon (GM in America) has 420,000 kms on it and still runs as if she's new. Over time I've replaced many parts but it's still cheaper than buying new ones.
Electric vehicles bring in a whole other range of issues and complexities with a closed market meaning repaires and upgrades will only be able to be done by specialist services.
