My 1998 bug now has 72,000 miles (bought it with 5,000 miles). So far, I have replaced the timing belt, spark plugs / wires, window regulators multiple times, alternator ($$$$$$$), wheel ball bearings, taillight (twice). The list is endless. Some of the parts that have been replaced are normal wear items, but even my mechanics have said that the car shouldn't be doing this with only 75,000 miles. Also, about every interior trim piece is sitting in the back seat. If you do buy one, be prepared to take the three layer door apart often to fix the window problems- they're notorious.
The car is fun to drive, like a go-kart. The gas mileage is ok as well.
Volkswagen should definitely redesign the interior trim parts and fix the darn windows!
