EZY,
Heres something you can print out and show your mate.

We brought our PA28 over form the US, one of the guys brought it with a ferry pilot.
You would need to extended range tanks and you would also need to get yourself IR rated as going VFR will probably kill you as complete VFR crossings are like chicken teeth!!! You would also not be allowed to ferry an aircraft over until you had several crossings under your belt with an experienced ferry pilot. Various other bits of kit are required as well such as liferafts, ELTs, dry suits, etc...
By coincidence, I remember seeing a website of a guy who had brought his SR22 over. Dont ask me to find it now though!
Donate my portion of the winnings to the Pprune fund....
