Through my investigation, I have found it was due to two issues. The first is airbags and side impact doors. Due to a lack of airbags and side impact door tests, they are not sold here. The other issue is that they were not selling too well here in the US.
I recently called two Land Rover dealerships. One here in the US and the other in the UK. Both spoke of the recent news, unreported as of yet, that Land Rover would be selling Defenders in the US again within 3 years. If you are considering buying one of the few older Defenders for sale at the exorbitant prices, we think you should hold out and wait. I have added some pictures and videso of the 2012 Defender 90 and 110.
