Cant be arsed to read everyone elses comments cos I want to go home from work but........
If a person has sent off for a V5, this should only take about 7 days to come back to them anyway........... BUT they should still have the Green part of the V5 which is as good as having the Blue part.
Basically Jim, if he aint got the Blue or Green bit of the V5, wait till he has before handing over any money.
