I came across a similar thing when I tried to buy an RRS last year.

Lovely car, high spec and the dealer told me it was originally an import. I paid a £500 deposit and rang my insurer to get cover. They would not insure the car for the value that I was paying because they said it was not an original UK registered car. So, I either bought it and the insurance cover was nearly ten grand less than what I was to pay or walk away.

I walked away and good enough the dealer gave me my £500 back!

jed.w  SDV6 HSE Sport2 - Santorini Black, Ebony Interior, Pano Roof, Things I haven't found yet!

TDV6 HSE, Java Black, Black Premium Leather, Privacy, LR Side Steps, Smoked Side Repeaters, SC Vents and lots of toys!

Thats the thing though. My car probably never left the UK and it was new at first registration, here in the UK. So there shouldnrt be an issue. IMO this is really poor customer service from LR. If they have a problem with their vehicles coming back into the UK via thge back door, then thats their problem. Not mine. They should honour the warranty and stop dicking me around.
