Turned up on Saturday morning with a puncture in the offside rear. Nick explained that there would be a wait of around 30 minutes as he was just starting on another customer's car - this was fine for us so we sat in the reception area while he finished the other car.
On our car, he immediately found the cause of the puncture - fixed it, fitted a new valve and rebalanced the wheel before refitting it. Really proper professional job - impressed to see him using a torque wrench to tighten the wheel nuts. Excellent job for £30 - highly recommended!
