yep methinks papasmurf may be correct on this one? my understanding is that if you've got comprehensive cover on your own vehicle, then you're automatically covered 'third party only' to drive any other vehicle that
a) does not belong to you
b) is already insured by its registered keeper
c) has a valid MOT cert
though I'm far from sure
regardless, it'd be very unwise make any unconfirmed presumptions with regard to insurance
