The Holden Jackaroo is a medium sized SUV produced by GM Daewoo. Holden Jackaroos are most commonly found broken down and abandoned on the side of the road thanks to the ultra unreliable 4JX1 diesel/steam engine that Isuzu decided to fit in them.
Some owners believe their Jackaroo's can be taken off-road despite the fact a Holden Barina puts them to shame both on and off-road, let alone a real 4x4. This common misbelief is due to the vehicles semi-impressive suspension flex, which can be attributed to the soft pine chassis that was jointly developed by Ikea and Isuzu.

Most Jackaroo owners have moved onto more reliable and safer forms of transport such as hitchhiking with Ivan Millat, the rest are broke and stuck with it.

"Nothing says failure like a Holden Jackaroo in your driveway".
"No I can't fix your Holden Jackaroo. Get your junk off my property"

The 4JX1 is an incontinent diesel engine which is best known for mixing diesel, coolant and oil before the vehicle can even leave the dealership. It was installed in the Isuzu Trooper and GM/Daewoo/Holden Jackaroo and was the most reliable part installed on those vehicles. The engine was developed in partnership by Isuzu, a toddler with a broken crayon, and Caterpillar (the insect, not the construction equipment manufacturer). 4JX1 owners can usually be found at home trying to repair their junk, or at the side of the road waiting for a tow truck.
"Do you sell any parts for a Jackaroo with a 4JX1?"

"No we can't make your 4JX1 reliable. No-one can"

"It's a 4JX1 thing. You wouldn't understand"
