Very poor ability and service. Terrible communications.
I took my car in after a brake failure, when my local garage hadn't been able to find a fault. I chose this garage as they had a diagnostic machine, phoned, checked the vehicle was compatible and had a long conversation with a very helpful guy about the fault and booked it in in three days later. Unfortunately the helpful guy seemed to have changed when I got there!
They didn't have me booked in, but did rather grudgingly take the car. Seven hours later they phoned to say they couldn't see anything wrong. When I asked what the next steps were, they said. 'come and pick it up, we can't see anything wrong with it.' When I arrived they handed me the key and started to walk away. On insisting on a conversation I discovered that 1) they hadn't put it on the diagnostic machine (despite having checked on the phone, theirs apparently doesn't work with my car), 2) hadn't checked the front brakes at all, 3) had found some possible evidence of a leak, but weren't sure (that appeared to be that).
On asking what I could possible do next, their only real suggestion was to put it on a diag machine - the very thing I had taken it there for. Three very difficult & expensive days without a car, and I'm no further forward. Their communication was shockingly poor, my very clear impression was that they didn't care at all, and given the apparently very limited inspection they made before handing me back my car, I'd not trust them with even the simplest thing. I managed to be polite, but left fuming.
