John is only too happy to accept the challenge.Meanwhile, back at the Vehicle Maintenance Unit, the team have to fix up a beat car whose tyres were slashed whilst on duty, John's favourite vehicle is returned in a less-than-pristine condition, and there's an ongoing investigation into Darren's facial hair.
