I reckon Starter Motor too, mine has gone yesterday morning, Recovery tried to jump start me and it didnt work and I have enough voltage in the battery. You can try giving it a wack with something long as the starter motor is in right a pig of a place, its down the back of the block, underneath the manifold towards the gearbox side. There's 3 bolts that hold the starter motor to the block and a white wire with a spade connector on the end, sometimes if that is dirty or not on correctly the car won't start, so it may be worth having a look at the wire first.
I've just been quoted £180 + Vat to have a new one supplied and fitted.
