Bought it, 14 years old but only 40,000 miles. Have driven it for two years now, adding over 20,000 miles, with no problems whatsoever. Note I owned a 1992 model before which I drove for 11 years without a single breakdown (sold it because of transatlantic move); based on that experience I didn't hesitate when I had the chance to take over this 14-year old little reliable workhorse.
overall a reliable car for being its age. the size is a little unsettling- it is often referred to as "space peanut" or "death trap". parts are expensive since it isnt a common car and all the parts you will find are after-market. the muffler alone cost $75.
Car was purchased for the wife to use to and from work. Best highway milleage was 42 MPG. In town average 28 MPG. Always used reg.87 octane. Very few minor problems. Would make an excellent student's car, or use around the city, and save the main vehicle for hitting the road. I would not hesitate to take it on a 3000 mile, or more, trip.
This car couldn't be beat for the price. Reliability was unbelievable, a very fun to drive daily car. Trips to Florida were fast and very cheap. Motor and transmission were driven to 424,000 kms. All I replaced was timing belt myself (2X) and the 3 piece exhaust was done a few times over. Yes I would buy a Mazda again.
