I see you are interested in S28's
We missed that size and wet from a S23 to a F33 , and pleased we did - it has transformed to comfort factor of our boating.
Twin engines does of course double the cost of fuel and service but the boat can be controlled much more easily - bow thruster too.
I do like the s28 but there do seem to be a lot of well worn examples. Good luck with
This one looks okay
