Yes I've taken my Morgan's to a local independent for the last 19 years for MOT but I do my own servicing etc. Ironically I called BB for an MOT 19 years ago and they couldn't do it at the time so that made my mind up, I stumbled across a small family run business and they said drive it in and we'll do it now and happy still with great honest service.
It has never impacted on the resale value not having dealer stamps and I know it's all been done.
