Recommend a bodyshop Bucks/Oxfordshire area

[biggles]

I'm starting the process of finding a reliable bodyshop to complete a respray of my 1960 1.5. The chap who maintains it is too busy to help so I'm in the unenviable position of finding someone who I can trust to do a good job.

I'm based near Thame on the Bucks/Oxon border - anyone have first hand experience of someone good in this area?

regards

Simon
