In my personal experience (more than 20 years driving and owning cars), the great majority of repairs I had to make to my cars where to the suspension (mostly ball joints, shocks, etc.), direction (universal joints, steering rack), brakes (seized calipers, leaking brake lines, etc.), and electronic/electrical stuff (all sorts of shorts, burned electric motors for windows regulators, problems with switches, door locks, etc.)
Correct me if I'm wrong, but current electrical cars still have the same suspension, brake and direction parts. And they have way more electrical stuff.
And the biggest problem for the longevity of cars (at least where I live) is rust. Now explain to me how an electrical car will be magically protected from rust? They're still build with a steel unibody and steel body panels?
