This is the shocking dashcam footage which shows a Halford's mechanic taking a customer's car for a joyride at almost double the speed limit when he took it in for an MOT. Shaun Ingram booked his Ford Focus ST in for a major service and MOT at Halfords Autocentre in Plymouth last month, costing £255. But when he went to collect his car, he was shocked to discover that a mechanic had taken it for a spin after his dashcam recorded footage of it being driven at 57mph in a 30 mph zone. Scroll down for video . Footage taken by a dashcam fitted by Shaun Ingram to his Ford Focus ST, which showed a mechanic taking a customer's car for a joyride at 57mph in a 30mph zone . Shaun Ingram, from Saltash in Cornwall, who discovered the footage, says it shows it was a pre-planned thing, not spur of the moment . Mr Ingram, 50, of Saltash in Cornwall, said that his camera recorded almost seven hours of footage, which included the mechanic swearing and boasting about test-driving the car. He explained: 'When I saw the footage I was left open-mouthed. The mechanic was abusing my car and my trust. 'As a nationwide company I thought I had nothing to worry about. But I feel very let down. 'From now on I will always wait by the car whilst it is being serviced.' Mr Ingram, who is a married father-of three and works as a large goods vehicle assessor for Dairy Crest, said that the dashboard camera was not switched but was on standby mode on a motion sensor. He said: 'I was not trying to catch anybody out. I bought the camera- ironically - from a Halfords store in Plymouth last year. The dashcam captured seven hours worth of footage after Mr Ingram left his car at the Plymouth branch of Halfords . Footage showing the car being taken out on a test drive captured by the dashcam. It also showed included the mechanic swearing and boasting about test-driving the car . 'I have it in for road safety purposes because of the way some people drive. 'I did not look at the footage on the Friday afternoon when I picked the car up. 'I saw it the next day and I almost choked on my pasty. The biggest file on there was the road test where the mechanic was doing nearly twice the speed limit. 'I then decided to look at all the footage. There was one clip of him reversing the car off the MOT bay and leaning over to tell a colleague ‘you wait til I road test this later.’ 'That shows that it was something that was pre-planned and not a spur of the moment thing when he was driving my car. Mr Ingram says the dashcam had been switched to standby mode and came on due to its motion sensor . 'There is another clip of him constantly swearing when he can’t find the key sensor. 'I have not been given his name and I don’t need to know unless I get a speeding ticket. 'There is no point getting really angry about it. But it is fair to say I was open-mouthed when I saw the footage. 'I took the laptop in on the Monday morning and the manager was very non-plussed when I showed him the footage. 'Had he apologised then I would have left it. But I have now spoken with the head office and the regional manager and still not received an apology. At least they have started to take it more seriously though. 'I look after my car - it is my biggest asset and cost me nearly £10,000 and it is disgusting that someone like him treats it like this. 'I would never have known about it if I did not have the camera. I did not know it would pick it up but it has proved to be well worth the money.' Halfords have explained that the mechanic who drove the car was a temporary employee at the branch in Plymouth, who has since been removed from this role. The company described his behaviour as “appalling” and offered to refund the cost for the MOT and service. The regional manager for Halfords Autocentres, Darren Stone, also told Mr Stone in an email that the mechanic’s behaviour was unacceptable. He said: 'He drove your car in what I can only describe as an appalling manner. 'I do not and will never condone that level of pure neglect which is why the mechanic in question has been removed from working within the Halfords Autocentre Group.' Meanwhile a spokesperson for Halfords head office said: 'We were really disappointed to find out that this had happened and that we have let the customer down. 'We are treating this isolated incident as a priority and can confirm that the mechanic no longer works at Halfords. 'Please rest assured that we take issues like this very seriously ensuring that our 300 Halfords Autocentres always adhere to all road test procedures.'
