My wife has fused discs in her spine and, despite much padding and cushioning, is reluctant to travel more than a few miles in my 2002 Peugeot 307 XSI which she finds too firm for comfort. There are hundreds of middle-aged Jaguars available at prices between £900 and £2500, but I don't know which ones may be softly sprung or a bad buy, and I'd be very grateful for a shortlist of other possible 'comfort' cars I could look for?
