The contract has been awarded to PCS (who also do operate the BHX service).
Apparently there are 40, V70s on order due to arrive late January and the Toyotas (14 I believe) were bought as a 'stop-gap' until the Volvos arrived!
I have to say that I've used PCS for a while now and have found them to be superb (actually better than Tristar if I'm honest).
