loads of minis have had new front ends and scuttles put on and in many case's vin plates were never replaced
so why should it be a problem
my v5 states on it "made from parts sum or all which may not be new"
and retained it's correct dated plate
have you asked the seller why there is no v5
you never know he might be a honest person
and have a genuin reason
he like hundreds of other mini owners in the past swap shells and parts
why does every one jump to the conclusion it must be stolen
if it's a good shell why scrap it
keep minis on the road not the scrap heap
