Just a tip - they may like they did with me try to charge you for an MOT service , prep and test (very vague and didnt know exactly what was included in this) - refuse to pay this if its under 3 years old as obviously you dont legally require it and also point out that speedo and fog are fitted as part of the ESVA test to make it road legal in the UK.
The exchange rate is very good right now so you should get a good deal - bare in mind the winning auction price is not what you have bid for the car but for the car , storage, auction fees, transport, deregistration but they dont break down anything whicj is major let down with them
