Opel Monterey: a large SUV with Isuzu tech, engines, and what to check
Opel Monterey — a large body-on-frame SUV, produced from 1992 to 1998 and based on the Isuzu Trooper. In Lithuania, it's known as a cheap and sturdy used SUV. We'll look at the versions, engines, and what to check before buying.
Monterey in brief
Monterey was Opel's SUV, manufactured by Isuzu in Japan. It's a two-length — three and five-door — vehicle with a body-on-frame construction and low-range gearing.
Thanks to its robust build and spacious interior, it was popular among utility, hunting, and family cars. In Lithuania, it still has its community today.
Versions — what sets them apart
The shorter three-door version is more sporty and agile, while the five-door is more practical for families and cargo. Buyers often opt for the longer version for the space.
During its production run, the car was updated — the front end and minor details changed. Later models are usually better equipped and well-maintained.
Engines and transmissions
The most common engines are the 3.2-litre V6 petrol and the 3.1-litre turbodiesel. Later versions also featured a more powerful V6 engine.
The transmission is either manual or automatic, with low-range gearing and selectable four-wheel-drive mode. The diesel version is more economical, while the petrol is smoother but thirstier.
What to check when buying a used Monterey
The key thing to check is corrosion: the frame, sills, wheel arches, and the underside of the body. A 4x4 often drives in tough conditions, so look for signs of impact underneath.
Test the full and low range gearboxes — they should engage without hesitation or grinding. Check the service history of the transfer case and cooling system.
Parts can be found through Isuzu Trooper enthusiasts, as many components are shared. Before buying, ensure the body numbers match the documents.
