I am absolutely over the moon with the exceptional service I received. The convertible roof was not opening properly, the main dealer told me I needed a new frame which would have cost me thousands. Somebody suggested I try Tech-One. I am so pleased I did. Not only did they find the real problem (which was not what the dealer advised), it cost me a couple of hundred pounds rather than many thousands. It did take a few hours to find the problem, but they persevered, found it and fixed it. I just need the sun to shine now. Thank you so much.
