If he's currently insured on a car get him to phone his insurance company and tell them hes viewing a car with intent to buy. Ask if you can have your policy swapped over to the ek9 (they generally won't take payment straight away) . Get the car drive it home , call back the insurance company and tell them you wana swap it back 9/10 there is no charge due to the change of cover only being 48 hrs .
