Buy the cheapest mostly rust free series 2 Land Rover Discovery ( 1998–2005 )
Install a mild lift kit, hopefully these come with diff lockers and other offroad bits.
Swap in a 5.3 Vortec, idk if that is a 5.3 but it should be close enough. Iron or aluminium either way is fine. Doesn’t bother me. Whichever makes more torque.
Install roof bars/ rack, and brushguard, don’t forget the lights. Fenders and snorkel.
Should look close to that, but painted Matte white. The engine would be kept stock, maybe a bigger radiator but that’s it.
