The 110's were made of typical glass until about 02. Some of the Tartans were also made of glass from 99 to about 02-03 that were made by the current ownership fof T&C. For me any how, boats made from about 05 or there abouts on in epoxy, I would worry to a point re the delam issues, and one that I know of with a gray deck instead of the bright white that it should be, due to more than likely a color mix issue at the factory, with that owner getting a number of different and funky reasons as to why it is gray, not white.
The 99's and 115's were all made of epoxy, not sure about the 121's, then you are not asking about them.
Other wise, to a degree, it will be buyer beware, as Novus has tried to sell the T&C lines assets to another buyer, they backed out. Leaving owners with out a warrenty, along with leaving the debts to the old company etc.
I also believe that if you really search, the BIG thread in the buyer area is still there.
