Timing Belt snapped at 105k - regular maintenance is at 60k, obviously never done.
Dipstick handle broke off (common).
Pilot bearing on clutch starting making noise - went ahead and changed whole clutch.
Great little car. Fun to toss around in corners - is like driving a go cart! Maintenance and repairs is reasonably easy and fairly cheap; I changed my clutch in my garage with a buddy's help, complete setup for less than 100 bucks. Timing belt change, which is the major maintenance item on this car, including a new water pump, assorted seals and gaskets, was less than $200 doing it in my garage.
I use this car for commuting back and forth to work. It gets approx. 33-34mpg on the highway, a little less in city driving. Seats are comfortable, but driver's tends to wear on outside bolster. There are a ton of aftermarket items for this car.
Update: I made this original posting a couple of years ago.
I am now at 150k miles on this car. Other than the timing belt and clutch, I've changed nothing else, and nothing since the last update (except tires). This has just about been the cheapest car to own I've ever owned. Nothing else has gone wrong, I've been completely satisfied with this car.
Tires make a big difference on this car. Originally I bought cheap tires to replace the originals that were on the car (they went 95k miles!!). They were lousy tires - got good gas mileage, but had crappy traction and wore pretty fast. The replacement tires I bought have dropped the gas mileage a little bit, but they're a lot stickier and the car's a lot more surefooted and comfortable ride.
All in all, highly recommended.
