Those things are approx the equivalent of $500.00 in the UK. God knows what you guys will have to pay.
They're a nice piece of kit and look neat once they're in, but everyone I know who's fitted one, including one UK supplying dealer tell me they're a bitch to install. What you're never warned on any site advertising them is that you have to cut down the Defender sun visors to fit them. In the pic look closely at the corners of the sun-visor nearest the mirror and you can see the vinyl doesn't sit correctly where it's been cut & shut.
