Well It's good they have at least one satisfied customer. I've heard a lot of horror stories and they've featured on watchdog type programs in the past. Maybe the ones round here are different but there are several examples of them doing work without being asked the one with the brakes is 100% true as it was an elderly friend of mine who was steward of a club I go to. The kwik Fit was opposite our club so he came back saying what had happenned and he said he didn't have the money, (incdentally, yes,£700 isn't too bad to change disc and pads all round, but it is if it's not necessary). We advised him to give them the choice, donate them or put the old ones back, they did the latter after initially refusing both options, when the customer offered to sign a disclaimer.
A female friend of mine went in for a tyre and they tried to tell her the exhaust was knackered, that is until she produced one of their own life time guarantees for the exhaust they fitted 6 months ago!
You must have the the Saintly version round your way, round here they're a bunch of rip off merchants that's stitch up their own granny for a fiver!
