Hello. Looking at buying a used 2017 Bennington 22SSRXP premium tritoon with a 150hp Evinrude. It is in excellent condition with many upgrades. Boat is really clean and motor has around 180 hours. It also has blackout package. Comes with trailer. I believe this is first year they made these. My question is how do I find what they are worth? I don’t find many for sale so hard to determine. Are there any major upgrades I should make sure it has? Thank You.
