personally think you're just a bit nuts selling her ...... . you're only 80 and many many more good driving years ahead hopefully .... but life has it's detractons too and you've sensibly assessed what's happening eh !
I was chatting yesterday to a guy at an antiques shop locally and his father-in-law at 90, has had his Ls400 for some 25 years from nearly new, usually garaged and immaculate too he says, and is still out and about driving it, but not so often now with the Yaris for shopping whatever ........
Your location in Scotland might limit a tad the potential buyers I'm thinking ........ let's see ........ as I said, it's " priceless " to the discerning buyer out there somewhere
Good luck
