You might want to look into importing the aircaft into the EU. If you travel from one EU member to the other, you are subject to VAT in those specific countries... Talk to the NBAA about it... HUGE fines may arise if you dont..
This is only the case if you are planning to fly
within the EU with EU citizens for commerical purposes.
If you have never been to Europe before I suggest taking an international procedures course. You are required to do so every 2 years for operations within the EU anyhow so this will be good excuse. When asked ,ie SAFA check, you must provide documentation showing such training has occured. This trianing is to include,ICAO, JARs, MNPS, RVSM, RNP-5, and P-RNAV (if aircraft equipt and certified).
I went to
www.trainati.com before my 1st international trip. I go every 2 years to stay current. Well worth the money.
Besides what was said above you will also need the following:
1. Enhanced Mode S transponder after March 31, 2007. If you have an elemtary Mode S you can get a case by exemption so long as you do not plan to fly over 30 hours a year within the EU.
2. A current HMU/GMU flight within the last 2 years. You can check to see if was registered with Euro-Control here:

If you are not registered you can have an HMU flight done over the continent or have ARINC do a GMU flight for you for around $2500 bucks.
I know that there are things that I have not mentioned or other folks have not said, but in any case you need to go to a formal training course.
Good luck.
