I live round the corner.
Bought my mini clubman JCW new from Williams stockport and they opened next to Trafford Centre which is really ideal as it saved me an hour and a half round trip in m60 traffic.
Had an issue they flat out refused to sort it, the minis have an issue the plastics going grey had this issue on the passenger side stockport sorted it. Took it to Manchester they said they wouldn't cover it. I had a headlight orientation issue and they returned it with me with the bolts that hold the light in missing. It was only when I broke hard that I found out the hard way. Although it had been in the garage the week before they accused me of crashing the car and it being repaired badly until they realised it was in the week before quickly went back on that accusation.
Car just hit 3 years old we had a slow puncture on a runflat and my fiancé needed to pick up her wedding dress in Glasgow... week before the wedding. She took it in they couldn't find any issues, said they had put it in a bath of water no bubbles so sent her on her way. I thought no chance so took it to a back street garage that was close for a second opinion, just pored some soapy liquid on it and instantly could see the bubbles. The wheel was cracked and not just a crack but it had a birds foot crack so split in 3 places. Bear in mind she was about to drive 400 mile round trip and she's not mechanically minded you could imagine what the consequences could have been. They were just going to let her drive off.
Absolutely disgusting, imagine if an accident had happened because of this a couple of days before the wedding. I was fuming.
Anyway after some negotiation they give her a courtesy car and off she went. Wheel was £600 they wouldn't cover it under the warranty as it was like 3 weeks over. We were a week away from being married and needed the car to get to where we were getting married and also for our honeymoon so there wasn't really time to sort so had to suck it up.
Anyway wheel arrives next day and they decided to take the rest off to check at this point. All 4 are cracked, and on top although I have owned the car since new and never had the tyres low on the car as it has pressure warning. Apparently the inside wall of the tyre had cuts as if the car had been ran low.
Long story short, full set of alloys and a new set of tyres all round. They were super difficult with the tyres because they wouldn't fit non runflats and 35 profile runflats all round on 19" wheels were absolutely the cause. I had to fight with them and all they could get next day was a mid range Hancook which had no rim protection at all on brand new wheels that were £600 each. With diamond cut wheels the combo is a nightmare waiting to happen.
In the end best part of 4K, although I bought it from Williams group there was no good will, no offer of help. By this point it was 3 days before the wedding and I had other things to worry about and we needed the car fixing.
4k, days before the most expensive day of your life was far from ideal.
As I picked it up the pressure sensors wouldn't work either because they didn't reset them so had to go back again.
Anyway it was pushed toward it being my fault and apparently they had never seen a cracked alloy before which we all know is complete BS.
I wouldn't even entertain going back again.
