Hi Alan....welcome to the Forum
Good to have you onboard!
There are a couple of specialist repairers in Bournemouth....Marina garage, although I knew them many years ago as a good garage, I couldn't comment on them nowadays as have no dealings but worth checking out....think they're Boscombe way?
Also, there is Hollybrook Jaguar in Ringwood (turning off towards Verwood)...again, couldn't tell you if they are okay as no dealings with them but worth checking out nonetheless.
Also, there is Dorset Sports Cars at Three Legged Cross and I do know that they have a very good reputation.
Let us know how you get on with any of these garages
Cheers, Trevor
