Minor electrical problems invariably arise in these older VWs (noises and lights going off for no reason), but at around 150,000 miles, the engine uses no oil and runs the cleanest of any car I've ever seen. After 2,000 miles, the dipstick is still clean. A friend of mine bought a Fox whose odometer was broken at 250,000+ miles, and he drove it for five years that way until the trans eventually started making ugly noises.
Easy to work on. Decent handling. Large trunk.
It's only got 80 hp, so it's kind of a dog, but it cruises well between 70-80 mph at relatively low revs. Its 4- speed trans is strangely well-designed, but speed off the line is an issue.
