true ive used the same garage for 6+ years now and they have passed the car or done little bits of work for me like
putting some redex (or something similar) in my clio when it failed on emissions gave it a blast down the road then it passed
my 405 failed on rear brake lines they passed it but booked me in the week after to check it had been done
my astra should have failed cause i had taken the rear seat belt clips out but they still passed it
these little things keep you going back to the same garage and a good garage would know this
