Our Cavalier's C20XE develops issues in London. Time for some TLC, but we need to get it home first!

We left the Cavalier in Sutton for two weeks after we picked up the Corsa. Upon collecting the Cavalier we found that it's not too happy. Running on three cylinders from cold, hard to start and the exhaust has split too. Does it have enough left to get us back to Scotland so we can get on and repair it?
