The stories do evolve as you get to know Harry and his ‘family’ and friends better. 🙂
Sorry to read you’re all at sixes and sevens at the moment.  Just remember to take a slow, deep breath or three from time to time – I find it helps calm the brain down from that horrible ‘panicky’ feeling when unspoken fears start to blow up out of all proportion (something I am prone to, alas). Good Luck the the Neurologist {{{Tharg}}} and let us also hope that whatever it is, the ‘thing’ isn’t too troublesome. {{{Mrs. T.}}}
Regarding cars – I can vouch for my Golf GT for comfort, at least. Firm, but not hard, and certainly not spongy. I wouldn’t last long with an overly firm suspension, either. You’ve got a Cooper at the moment, yes? Probably no good for me if it’s no longer any good for you, but I am hoping the Countryman might suit me come renewal time – officially next February, but I’ll have less than 12 months on my PIP by then, thanks to the nine month ‘Covid’ extension. I had hoped the have PIP done and dusted by the end of this year. Oh well.
