its Registerd as a V plate and Everyone says its Either a Private plate or its a Ringer

Ive just Noticed on the V5 it says Engine number Not Known,
Iknow Most of the cars History for the past 2 years it was Bought from Auction By a good Friend off mine And it was Cheked out,
Ive just found off him the Car as been Imported from Austrailia,
Is there Anyway of Finding out Where a car as been imported from?
Iknow some cars Are dropped back a Year when Re-registerd but id like to find out its origian year of Manafacture and was it originaly a right hand drive or a Left Hooker,

Also when I insured this car they had trouble getting it up on there Data base they had to manualy load in the Details -is this Normal for an Imported Vehicle?,
