Doubt it would work if you've left it for 3 years.
I've dealt with him. Not a nice bloke. If you need car work done go to the A6 MOT and Service Centre near there instead.
May actually get mine done....needed doing for 3 years but never bothered, only a few miles from me.....HOT
If you live near the West Houghton branch of ATS it's worth popping in to see Karl Pilkington in there. He's one of the managers there and is as miserable and dumber then the real one. Wouldn't get any work done there though as they offer a terrible service, mainly due to the Karl Pilkington clone.
Good price. watch out for the expensive add-on of a "filter" at £12.99 or whatever. Usually just clean the debris out of the old one (nerd)
