Alternator - the ONLY major problem I ever had. $30 to replace.
Not fast, but very adequate, indestructible, and gets 30 mpg.
Good car I have one.
I had a '72 Bug once back in the 90's. Loved that car. Took it everywhere, to Canada and back. Didn't miss a beat.
Loved the sound it made, that Bug smell, feeling like you were going fast, but really not.
Although it had been mistreated and sold to me in shoddy condition (our mechanic was going senile, but we didn't know it then when he checked it out when I got it) and he basically put the engine in wrong/backwards -- once I finally got it fixed by someone who knew what they were doing, there was no stopping me and that Beetle.
Simple, fun, cute car.
