Well. Assuming you're not colour-sensitive, There's a gorgeous Manual Cobalt Blue with 32k miles for Ā£53k at ASM in Buckinghamshire.
Cambridge OPC have a white Manual with c35k miles for Ā£70k which is very strong money even if it would come with the 2 year warranty.
Hofmans in Henley-on-Thames also have a white manual with c27k miles for Ā£67k. Hmm
Esoteric Auto in Beds have a nice Black Manual for Ā£48k but it does have a high 62k miles on. Now given your limited mileage this could actually work in your favour as you won't be adding that much each year (?)
There's some higher mileage ones here too, but they'd need a proper think-about, even though most people wouldn't worry too much come resale if they heed the 'History, Condition, Spec, Colour, Mileage' mantra
(Ignore the muppets who manage to slot 996 Turbos into the 997 category!)

PS - have I seen you at either The Hare in Roxwell or White Elm in Danbury for breakfast meets? You should give them a go if you haven't!
(Hare is 1st Saturday each month, Danbury is 2nd Sat each month
