Ok, right, sorry im not in work today otherwise i would of been able to help.
BUT
just becaused its not coming up on the IVS or kerridge system does not mean it has no history!
It could of been a Military car, or it could of been a Staff car!
Both of the above reasons mean a car is not traced on the history front. My adice would be, get it HPI'd, and make sure that you scrutinise any receipts he does have!
Sytner, 'should' have the car on their personal database as opposed to national one.
failing that call, the supplying dealer.
