I've finally come to the realisation that for me there is no comfy car on a journey over 6 - 8 hours! The very act of sitting there in the one position (given some minor fidgeting) leaves me stiff and aching. Tried everything; Volvo, Mercedes, BMW, Porsche etc. but have come to the realisation that it's my age. That said, a recent eight hour drive back from Snowdonia along A and B roads in the Plus 4 left me in the best shape I've been in after such a length of trip for some years. Ears ringing a bit from the road noise but the rest of me ok. We've both always found the Plus 4 comfy, which was a revelation given that the reason I didn't try one for years was reports in the motoring press of discomfort and a harsh ride. (Yes, it does crash a bit over big bumps!). I don't read the motoring press any more.
