We see some fairly radical machinery come up for sale on occasion, but few creations manage to raise our eyebrows so high as Project Sea Lion. Created to nab amphibious land speed record, the machine uses a Mazda 13b rotary engine for propulsion, and its creator says the drivetrain is good enough to launch the vehicle to 180 miles per hour if there's enough roadway. Given that the current record sits at 125 mph, the Sea Lion should have no problem nabbing that title.

Top speed on the water may be a bit more cumbersome, however. The quickest amphibious vehicle can get to 60 mph right now, and Sea Lion's builder says the creation will need more horsepower to make that happen.

He suggests a Renesis conversion. We tend to agree.

Made from tig-welded aluminum and a variety of CNC-machined components, the car comes only with a bill of sale. That means we can forget all about driving/floating this thing to work. If you like what you see and what to give the amphibious land speed record a go for yourself, Project Sea Lion is for sale over at Fantasy Junction for the low price of $259,500. Scroll down for a quick video and be sure to check out Fantasy Junction for more details and photos.
