My 2011 Plus 4 was too uncomfortable for me and had vague steering when I bought it in 2018. After having it only a couple of weeks, I arranged for Williams to fit SSL suspension upgrades to front and rear, which substantially improved the handling. Very precise steering, and slightly smoother ride.
Since then, I did about 10,000 miles in 18 months, and it felt very comfortable most of the time - but still not good on rough surfaces....
I also experienced petrol fumes sometimes, but can't remember any particular reason for it!
