1996-2006 Ssangyong Korando
Although it was never sold in the United States, the 1996-2006 Ssangyong Korando was a quirky SUV from the 1990s that used Mercedes engineering. The drivetrain and power plants were licensed by Mercedes-Benz and the styling was reminiscent of a Jeep CJ. The off-road capability of the rig was undeniable and it instantly became a hit (via Bring a Trailer).
The Korando never made it over to the US market due to stiff competition but the SUV was definitely a rarity. The gasoline I-4 and I-6 options were the only way to go and they offered capable performance. There are quite a few boxy SUVs from this era worth mentioning and the Korando is at the time of the list.
