Thanks yes aware of those cost but had a look at the UK dealers there putting about 50K on top :(Good luck. Dealers are not permitted to sell direct to overseas customers, although you may find one that will "sell" it to someone local who will then sell it to you.
I'm sure you're aware there will also be 10% import duty to pay on whatever price you buy it for (including any dealer mark up) and the 20% VAT on top of all that.
Unfortunately, buying a brand new US car isn't easy :(
It might be worth you speaking with Bill Shepherd Mustang (Byfleet) or Clive Sutton (West London) as they are bringing some in, albeit at a hefty premium.
