The only thing that I have had to do to this car is replace the distributor cap and spark plugs. Other than that it's been a great car. Gutless? Yes. But it gets great gas mileage.
I like the 40 miles per gallon, but this thing is pretty gutless. So if you're looking for power and good accelleration look somewhere else. But if you like good gas mileage and a dependable vehicle, (at least mine has been) this is a pretty good car. It's been a great first car because the gas mileage is great, and the parts are cheap. I was quoted $400.00 for a rebuilt engine. A bad thing I had to deal with was high insurance. I'm not sure if it has so much to do with the car than just my age. Obviously if one of these things got in a wreck it would be totalled, so that could be a factor. Some other downs to this car is the cramped room inside and the loud road noise at high speeds.
I have a 1994 Metro, its my work car. I get 50 MPG, the road noise is not bad under 65 MPH,, anything over 65 is a death wish in this small car.
I have a 94 Geo Metro. It's a VERY fun car to drive, though it's not visually appealing. I, too, am incredibly pleased with the gas mileage. My biggest concern in this car is not the insurance, since what I save on the gas goes to insurance, rather I am scared stiff about getting into a wreck. Just being rear ended could ruin the back half of the car and injure anyone unfortunate enough to be stuck in the back seat, which is a very cramped space. I can imagine a full wreck on a freeway to end up with my death. I'd say this is an EXCELLENT car, however, as long as you don't plan on going at high speeds constantly. For inner city and suburban use, I'd give this a 15/10 because it's so cheap to maintain/
