Picture the scene, we have an ultrasound scan booked at the hospital early on a miserable, cold and damp morning. Jumped in the car with my pregnant wife to find that it just wouldn't start. Somewhat frustrated, I pushed it off the drive to jump in "the other" car, who started first time and made it to and from the hospital without problem.

Would anyone believe that the troublesome car was a VW Polo, and it was trusty Dolly who got us there on time? It's what happened, honest!
