General Comments:

There was a time that I lost complete faith in this vehicle at about 80,000 miles when everything started to go wrong at once. But once I repaired everything, it was good for a long time.

Now my biggest problem is rust and I believe the reason was because I keep it in the garage for a year or two mostly in the winter. The condensation and moisture in the garage just soaked the metal and caused it to deteriorate. I believe if I had not garage kept it, it would have a lot less rust then it does now.

This vehicle has been my workhorse and my friend. Even with 105,000 miles on it, I would have not qualms about driving cross country with it.

Faults:

At 100,00 miles I've replace the water pump, battery, alt, rotor, and spark plugs. And it needs a new timing chain. All things that would normally need replaced.

General Comments:

The exterior and interior has held up beautifully. This is my second Blazer/Jimmy. I sold the first one because it only had 2 doors. And for a family I need 4.

Faults:

As far as what has gone wrong with our truck, just the regular replacement items, wipers, belts, muffler, tires, gas tank, heater core.

General Comments:

The truck has been very reliable - always there and working when we need it.

We did get good miles per gallon when we took it on the road.

This is our second Jimmy, and we love them. Also purchased new, a l999 Jimmy.
