Being about 40 miles from the nearest Morgan dealer I have been using a local garage for servicing. They have a history of Morgan ownership and many other local owners use them and, up to now, have had no reason to complain but I've just realised that they don't appear to have been doing some tasks that I would have expected to have paid for. I am not mechanically minded so it is possible that they may not be necessary but it maybe that I have booked a "service" and they have simply checked the usual stuff and topped up or changed fluids. In their defence, there has been regular work on brake and suspension items.
Every other car I've had has been serviced by the appropriate local dealer who has been only too eager to remind me of this year's expensive replacement which i could always check in the Owners Manual. No such document came with the Morgan
The sort of things I had in mind were: Cambelt(s) (although I don't think the Plus 8 has them), Clutch and Brake fluid replacement (also master cylinder). You'll have a better idea than me.
