Buying used triton

#1
Hi everyone, new to the forum because i am trying to get informations on a boat i want to buy and i am having a hard time finding.
So the boat is a triton 18xs 2010 with a 150 optimax. Boat looks clean and low hours (160). It was bought in 2012.
I am looking at differents years of the 18xs and looks like the 2010 is completely different than 2011+
Am i wrong on this? How is that boat? Is it a good buy?
Any info on these would be greatly appreciated.
Thank you very much
Max
