I'll second Cumbria...well it was the land of my birth so Gods Country....but I'll also second the far north and west coast of Scotland!
Getting back to reality for Neil, if you don't want to get too far away from the factory, there is a nice circular route which takes in some nice roads and a nice pub or two...and holders if you want to look at some motoring goodies! The A44 from Powick just south of Worcester up to Bromyard is a nice road with some nice bends, views and a good run up over Bringsty Common and down to Bromyard (nice pub up there on the common, the Live and let Live although its down a rough track which can be a challenge to a Morgan!) Holdens is on the left just before reaching Bromyard. There's a selection of roads taking you back towards the west side of the Malvern Hills, aim for Ledbury which is a nice place to drive through in a Morgan and then take the A449 back up over the hills by British Camp ( another nice watering hole opposite the car park up there) and then drop back down to Malvern.
