Cracked air intake at 75,000. This is a known problem and is easily repaired with duct tape.
Replaced CV joints/wheel bearings at 100,000. Cost about 400.00.
Have gone through 3 stainless steel mufflers or one muffler every three years.
Replaced transmission at 130,000. Cost for a used one was 1,500. Probably broke due to lack of engine oil (says my mechanic).
Replaced clutch at the same time as transmission. Cost about 200.00. While they were in there... it probably did not need one.
Seat belt light recently stuck on (150,000).
Great car overall. Only stranded me once when the transmission broke. Engine is strong even if the other parts of the car are starting to wear out.
I have not maintained the car through its lifetime and it has hung tough. Oil changed every 6K to 10K miles or until the oil light comes on. Did not flush radiator for until 140,000 miles had passed. No AC recharge and it still blows cold. This car is bombproof.
Only complaint is the chassis noise. It is rather noisy at highway speeds due to finish of doors/windows.
I have had this car on one cross-country trip, many trips to Moab, etc. and it has never failed me. Love this car!
I also own a 1991 Mazda 626 Touring Sedan with 191,000 in the clock and still going strong. I have replaced a clutch at 150,000 and a couple of CV boots. Still has original muffler. Great car. I wish they still made them as I have not had same luck with my 1998 626 ES.BJ.
