Some Cadillacs have been sold as RHD. The Seville STS from the late nineties and more recently the CTS, STS and the large estate crossover one whose name I've forgotten. I'm also fairly sure the Hummer H3 has been sold here in RHD.

The Chevrolet Blazer and Ford Explorer have been too. I can't think for sure on any other Chevrolet or Ford models. The Camaro was tried at the same time as the Seville and Blazer but I think LHD only.

I cannot remember if the Corvette has been sold in RHD but it has been officially imported at the turn of the last decade and after a gap of a few years has been sold here recently.
