General Comments and Impressions

The Isuzu Trooper has proven to be one of my favorites. Form follows function in this boxy, tall vehicle designed to take cargo and passengers through remote, challenging terrain. The Trooper functions well up to 3.5 rated trails, and the rear suspension has excellent wheel travel. In my opinion, the Isuzu Trooper is the best mid-sized SUV value on the market. A 2 year old S model will sell for less than $16,000. A stock trooper will require a shock upgrade before heavy off-highway use. The factory shocks are under dampened, and cannot control vehicle pitch in rocks and crossed axle terrain. The Trooper makes for an excellent expedition vehicle platform, with low cost of ownership.

Reliability: Excellent

No scheduled or unscheduled repairs have been required. The vehicle has had perfect reliability despite heavy off highway use. Of particular interest is the brake system durability. After 70,000+ miles the brakes have NEVER required replacement, which is astounding considering the weight of the vehicle.
