Hiya,
Well - my problem is rather strange one. Few weeks ago i finally finished my importing saga (imported 300zx from Guernsey). Submitted all paperwork to DVLA, paid all the fees, etc. 15 days ago received all paperwork (V5 / tax disc / new number plate papers, etc). However - i cannot insure it as its not in database! None of the insurance companies can see it online. Even if i try to do HPI check - no such number exists!
Already wrote few mails to DVLA - they responded - we did all as we should, speak to your insurers...
