Anyone have a Mariah 212 Shabah? Looking for info?.

I?m in the market for a nice used 21? bowrider. I?ve stumbled onto a really nice 1995 Mariah 212 Shabah with 220hp 5.0 power that I?m thinking about going to look at. From the pictures, the fit and finish of the boat looks amazing. The thing I?m wondering about, and what I can?t find much info on is how they handle rough water. The lake that I usually boat on is full of cruisers and houseboats that really stir up big waves. I?ve been in some newer 21? Crownline?s and Four Winns and they seem to handle that 1?-2? chop pretty good. How do the 212 Shabah?s ride in rough water? Also, what kind of performance should I expect out of the boat as far as fuel usage, and top speed? One last thing?.being an older boat that is close to 20 years old, should I be worried about any hull or transom issues?
