Heater core has a small leak.
Drivers side seat rail partially broke (easy to fix).
Thermostatic fan clutch failed, another expensive part.
Water pump was wrecked when the fan clutch failed, not too expensive.
Front brake caliper seized and had to be replaced.
Carburettor is worn and I had to add a spring to the throttle linkage so the car would idle at the right RPMs.
This car is pretty low-tech (mid-1970s technology), but it is tough, can really absorb a lot of abuse, and is amazingly reliable considering its age. During the time I've had it, I've really had to put very little money into fixing it.
Small, not very comfortable or luxurious, but great transportation.
These rear-drive I-Marks are not very common in the U.S., but they're excellent cars.
These cars were basically the same as the earlier ('75-79) Buick Opels, and very similar to the Chevette; most Isuzus gave you this, a rare car with common GM mechanical parts.
I acquired a 1984 1.8 Isuzu I-Mark in 1999, from my dad (He purchased in the early 1985). I drove it for around 4 years and the carburetor started failing... We sold it to our neighbor and to this date (24 years and 247,000 miles later) is still working good.. Very inexpensive to fix and a very tough car. I'm actually looking for one just ot have it becasue it was fun to drive... specially after watching some Opel Kadett C videos with velocity stacks on them doing slaloms and hillclimb in europe. Is very reliable and the only problems with it were the carburetor and some rust...besides those, that car only needed gas, oil and coolant.
