Came across this thread researching Olivers. Coming from the sailboat business, interior white glass is really not an issue providing it's offset with accents, just look at any production sailboat website, like Beneteau, beautiful interiors. You can also epoxy paint
any interior with whatever color you want, it's done on boat exteriors every day.
have made the first step with their Fiber Granite option as per previous posts, I think it softens the interior a lot, add the right fabric, some warm floors and change out the mirror overhead doors - you've got a really nice interior. It boils down to contemporary vs traditional, I think Oliver is a refreshing option in terms of the interior.
Robert is right on the labor costs of cleaning out the lines, colored gelcoat is not that more expensive, there is a reason why boat manufacturers only offer white interiors.
