Yes, it’s easy enough, either use a friend’s/relatives UK address - or just go online and setup a standing order, I’ve had no issues using my Manx address for that. Then as an earlier poster said they write to you - by which time or soon afterwards when it’s Manx registered, cancel the standing order - I usually send them an email saying the car has been exported, I never hear anything further. As you say the most important thing is to get the full V5, don’t let the seller send part to the DVLA, most dealers inform the DVLA online anyway so the V5 stays intact by default.

NFU include breakdown cover (just recovery not the full monty) with their car insurance. At the last renewal the price was too high so went elsewhere and needed separate breakdown cover, looking around I chose Green Flag which looked the best value, I’ve never claimed but their reviews are good. AA and RAC are reputed to be best but expensive.
