Sorry these questions have probably been asked before :- what's the deal with bringing in cars from the continent.. do you need to pay tax at customs ? how difficult is it to uk register? anything else to be considered?
have you read this? i c.b.a. to read it myself but it's always best to check direct gov for the law... http://www.direct.gov.uk/en/Motoring/BuyingAndSellingAVehicle/ImportingAndExportingAVehicle/index.htm
not done it yet but my bay is swedish so gotta register it soon, but have been to local dvla office, there is no import duty in within the EU though you still have to fill in the paperwork, you can drive it or trailer it no problems, duty is usually paid if required when registered if not already paid at the dock etc. log book or equivilant is always useful to have, still need to mot and isure to register as with any other vehicle.
