I got my brakes done on my 110 (in winter) by a reputable shop. Picked up and went to drive a long distance in appalling snowy weather. Brakes felt odd. Went under and found a sh!tload of mess with leaking unions and sagging un-secured pipes. Took it back, owner apologized, said his apprentice did the job and explained he (owner) or other senior mechanic normally check-over and test run any jobs but this one had been missed, and they busted a gut getting it done right asap. Bill was discounted. AND next time I went in - apprentice was gone, he'd actually been dismissed as this was a last chance failure. It does happen.
Other not-so-good experience was our smooth running and well serviced Peugeot estate car put into authorized dealer for service and new glow plugs. Sounded odd afterwards = more rattly (for a diesel). A week later on motorway, my partner driving, the engine failed catastrophically at 75mph in the fast lane. Block split in two, rods out the side, all sorts of mess. Luckily we got saved by a driver behind who got the oil in his face and was able to slow all the traffic to let us cross the other lines of traffic and get off the road.
Got it hauled home (to relatives house) and I had a look under the bonnet. What did I find on the glow plugs - two old nuts, two old nuts, two old nuts, one old nut and one new nut. Where did the missing nut go? Inside the engine I suspect. My suspicion is that they pulled the plugs out and dropped a nut inside, then just gave it back to us. Insurer agreed that was likely but said we'd never prove it.
Car went to a big company we saw recommended that replaced engines. That was the REAL start of the trouble. We had the car back briefly and in a terrible mechanical state, took it back and never saw it again for over six months. Getting it back involved armed police, anti-terrorist officers, customs & excise and trading standards staff. Turns out the garage owner and staff all have criminal records, and owner is currently in jail for damaging the spine of a customer who complained, and who he smashed face-first onto his engine block then battered several times with the hood and damaged him severely. Their 'garage' is believed to be a front for all sorts of nefarious doings, so much so that Trading Standards refused to help us as their Risk Assessment meant "we cannot send staff in with you because of the risk to them, you must go on your own". Well thank you!
What this episode revealed about the complicity of big credit card companies in the scam and their failure to assist formed part of a formal complaint to Government which found in our favour and against the credit card company, so although I lost a year of time messing about and pursuing it legally, I won and was reimbursed much to the disgust of the credit card provider.
And to finish - I had my chassis replaced with a galvanized one by a garage run by two young guys. They put washers under every nut, ran my brake lines through clear plastic pipe to protect them. And undertook a multitude of other small things that were not part of the contract, and were not paid for, but just did them anyway because as they said "we like to do a good job and we appreciate your business".
There's all sorts out there.
But - final thought - if the Ky guys have offered to make it right with your brakes - I'd give them the chance to do so. Then report back and give everyone else the good (or otherwise) news.
