It didn't pan out simply because nobody followed through. At one time I was looking into it, and XJguy was also doing so, although neither of us knew the other was doing it until later. I gave up because I couldn't find a dealer to sponsor importing them, and also because for some obscure reason the e-mail address I had for their director of international sales suddenly stopped working.
I had gotten as far as confirming that their agreement with DaimlerChrysler allows them to sell anywhere in the world. The gentleman said he thought they could sell them here, subject to meeting the requirements. The Super Cherokee uses a US-spec catalytic converter. At the time I was corresponding, they did not have an air bag steering column, so a US-spec airbag and steering column would have to be fitted. I don't know if dual airbags are required -- if so, the entire dashboard would have to be replaced.
And I didn't get to verifying if the Beijing Super Cherokee includes the currently required side impact beams in the doors.
I sure would like to own one of those stretched Super Cherokees!
