The Sea Lion sets sail.

Building an amphibious car has been one of the more vexing challenges for transportation engineers over the years. Some are fast on land and slow in the water. Vice versa on others. It's hard to build a vehicle capable of handling both modes.

Over the past six years, designer Marc Witt has built a prototype that can reach speeds of 125 mph on land and 60 mph in the water. The Sea Lion, is in competition with 25 other models to claim the title of the world's fastest vehicle capable of both operations.

Now, the Sea Lion can be yours.

For the price of $259,900, Witt is selling the Sea Lion on an auto enthusiast website called fantasyjunction.com. (The site is safe for work; we checked). The vehicle features a Mazda Rotary 13b engine and four-speed transmission.

"I am willing to continue working with the buyer on all future modifications," Witt writes. "I will remain available as a consultant, engineer, machinist and psychiatrist for whoever decides to venture further into the amphibious record books."

Competition between Witt's prototype and the 25 other contenders for the title of World's Fastest Amphibious Car is somewhat unofficial – there are no official rules to the contest and each year, one builder proclaims their performance better than the rest. Guinness Book Of World Records, however, will verify a true winner should a conflict develop.

Witt says the current Sea Lion is limited by horsepower in the water, and the next owner should consider upgrading the engine to keep pace with competitors.

"The next chapter of this project is to provide an ultimate engine and begin speed trials," he writes.

      Ubokia Is Similar To Craigslist...After hearing about Ubokia I just had to rush over to the site ( http://bit.ly/TryUbokia ) and see what all of the buzz was about. I was amicably surprised with the ease of use of the site once I signed up for an account and was able to gain access into their site. The sign up process was very easy and took only about 1 minute. The web site is very straight forward to navigate also. You can find offers of all sorts of products and services with a simple entry of a word or product in the search box. Results came quickly and was surprised to find many really cool items listed cheap! You can also place a want ad. This was very easy to do also. I wanted to find a new cell phone that was compatible with my carrier and got many responses the very first day. I now have a new cell phone and only paid $10 for it and it works perfectly. It was a pleasure to set a want ad and simply forget about it. Sellers contacted me! I know you will like using Ubokia ( http://bit.ly/TryUbokia ) as much as I do. Give it a try and find out for yourself how easy it is. BTW It's fun too. I smiled the whole time!

      I hope this thing is capable of going under water because that's where it looks like it will end up.

      Boy AOL staffers can't even check the facts right in front of them, can they? Article says top speed of 125, video says 180.

      My best friend has announced her wedding with a millionaire young man Ronald. They met via RichLovesC0M....it's where for meeting millionaires, who are searching for their special someone. It's worth a try! That's, beyond a shadow of a doubt, the dumbest thing I've ever seen. A quarter-million bucks for an oversized waverunner that, unlike a waverunner, only carries one person. Plus, it'll carry one person but 2 bikes. WTF?!?!

      The cars that can go from land to water have been around since the middle of the last century. They weren't very fast but the technology isn't even close to being new.
