it's only covers not the seats so I cant imagine postage being tooooo much, I was quoted $730 for two tone seats, piping and door inserts. So, I guess with shipping maybe like another $100 then tax on top you are still no where new 1k let alone £1,600 - however, if I get some i'd pick them up whilst I was over there and bring them back to avoid shipping and customs charges!
Fargo is the best person to ask and advise as he has done the process before.
