I understand that the RX markets differently all over the world so here is the spec sheet for the Limited model i am talking about:

I live in New Zealand so all RX's are AWD and the limited model i want to buy has most options standard. The only options are, Panaroma roof, Mark Levenson Audio and Rear entertainment.

The ML should be the same as everywhere else but we don't have Blue-Tek here.
