Question: import or sell/swap '79 bay

hello, I have a 1979 bay originally from California, then UK and now in DK. No rust although needs some care and attention. I drove it over and the engine failed on the way. Some blue smoke so not good news. I now must decide to either fit a new 2 lire engine and then pay import tax so I can drive it in DK or sell now and buy a Danish campervan. I do not know how much tax that I would pay here in DK but I heard that it could be 10,000 Dkr. Can you give me advice on what you woud recommend - sell or fix and tax. Thanks, Gavin
