Hi Everyone, My husband and I left

Hi Everyone, My husband and I left the UK over a year ago (I'm French and he is Italian). We lived in the UK for 5 years. We decided to keep our UK car with us to avoid having to buy one in Italy when arriving there. However, keeping our car has become an issue (we are now over the 12 months period). We would like to bring it back to the UK and sell it. I was wondering if, from your experience, you could help us clarify 2 points.1 - Because we were not driving in the UK, we didn't renew the road tax. Is this going to be an issue to sell it in the UK now? 2. We are no longer resident in the UK. The V5 registration address is still showing our old UK address. Would the DVLA accept a foreign address to be shown on the V5 doc? Would we still manage to sell it to some businesses buying cars straight away?Thanks for your help.
