Hello, I have a 66 plate Cupra Black. I bought it from Lookers Seat in Manchester in 2017. They were the first registered keeper. It had been intended for a member of staff who moved on, or so I was told. The car had only done 60 miles when I bought it and had only been used as a demonstrator. I spotted some bubbling and rust on the roof before Christmas 2019 - just before the 3 year warranty expired. I notified my local dealership - Letchworth Seat. The car was eventually inspected and found to have a greater thickness of paint on the roof than elsewhere on the car. On that basis, Letchworth rejected the request to repair under warranty because they believed the roof had been repainted/resprayed at some point. Manchester denied knowledge and provided a screenshot of the vehicle history which did not indicate any tampering had taken place. I contacted SEAT CS to lodge a formal complaint feeling that someone was being dishonest. Having spoken to both dealers, Seat CS said that were unable to take it further and the case was effectively closed from their point of view. They advised me to go to the Motoring Ombudsman but this feels very unsatisfactory. I was about to push the button on a new Cupra but won't now. I am raging at this. I would welcome any advice as to what I should do. Many thanks.
