I didn't have to spend much on it for the first year I owned it (bought it used with 176000 miles on it for a couple hundred bucks).
Now just replacing the things that wear out at 100000 miles or more.
This car is peppy for a small four cylinder and although it has lived two lifetimes already, after restoring the above components, it should last at least another lifetime. AND it gets 45 MPG.
Parts are cheap, but not available all in the same place- ya gotta hunt for 'em sometimes.
The car is also an Opel Kadett, so parts for much of that car work on the Lemans as well.
