The only item to need replacing over a three-year period was the starter. Not that I needed a starter with this car... it was so light, I could push-start it by myself.
Other than the starter, I just regularly changed the oil.
This car was the first one I ever owned. It was reliable enough to drive me back and forth to school everyday for three years, was spacious enough to comfortably seat myself and three of my friends, and it required very minimal maintenance. It didn't have a whole lot of power, was a little scary on the freeway, and, of course, didn't have air conditioning, but it was perfect for what I needed it for - getting me to and from the places I needed to go.
The 1965 VW Beetle had a 1200cc engine, not 1300cc. That came out in '66.
