Let's make the high-end sport cars cost multiple millions too then, if we want to keep it realistic, eh? The point is that nobody uses boats currently anyways because they're too expensive, raising the prices even more wouldn't change anything, nobody would buy them.
I would buy this in a heartbeat at 70k/100k region. Even the Dodo is expensive! Dodo should be lowered to like $200,000 ARD from it's current $600,000 ARD price.
