Dear Ian
Am just writing to thank you for carrying out a highly skilled job to repair bodywork on my much valued car. I watched from time to time as you carried out the complicated repair and it was obvious that not only were you highly skilled, but were also extremely diligent. It was also very noticeable that your priority was to achieve a first class finish, and that you did not work to any time constraints. In addition your price was very reasonable. I will be happy to recommend you to anyone, and indeed I have already commended you to some friends should they scratch or dent or require respray repairs in the future
Steve
