Yes this sounds good for Halfords.
I've seen many posts referring to Halfrauds and I think that this often very unfair.
When it comes to Halfords Service & MOT centres (which I have never used) then as far as I can see Halfords have a huge marketing opportunity and to take advantage of that opportunity they have to be 1) no bull**** 2) honest 3) capable 4) no axe to grind and 5) exceptionally price competitive. They will not make friends or money from extracting money from customers on dubious MOT issues etc.
Long may this continue. Having said this Halfords are currently trying to revitalise all there regional service and MOT outlets to get back into the game so given this it will be prudent to monitor "the policy" over the next few years. It could be that once they have regained a sizeable market share and reputation they could be a little more account book critical in the "failure" criteria and cost to "get road worthy". NOTE! I'm not pointing a gun at Halfords. All companies play the market and at this time Halfords are trying to increase market share, reputation, cost effectiveness, etc. so as always there are some great deals and service to be obtained out there.
LONGEVITY - this is the killer service marker be it price, quality, etc. etc. AND SADLY MANY organisations take the short term path to success and fail in the long term path.
