Three Very Cool Submersible Vehicles on 'It's Worth What?' (VIDEO)

Half the fun of watching 'It's Worth What?' (Tue., 8PM ET on NBC) is to see all the fun things they spotlight for the contestants to try and guess the prices of. This week, we fell madly in love with the submersible vehicles they spotlighted for the mother-daughter duo.

The pair had to arrange the items in order from cheapest to most expensive, but they forgot one cardinal rule of automobiles: Luxury convertibles are always way more expensive than a recreational vehicle, even if it does convert into a fishing yacht.

While it sounds fun to be able to go below water in a convertible, the added need of scuba equipment takes some of the fun out of it, while the RV/yacht would probably blow your mind if you saw it while out on the water.. The dolphin diving recreational craft looked like the most fun. Where do we sign up for rides?
