>> months are a time when a lot of people like to hit the water and kristen found a way to do it without ever leaving your car.
>> reporter: the joys of summer. the open road , a convertible, a lake. that's not good unless, of course, you're driving an amphicar.
>> which direction is highway 55 ?
>> part car, part boat. there are only about 400 left in the world. manufactured in germany for a few years in the 60s they now sell for 50,000 or more.
>> this looks like the most fun vehicle you could ever have.
>> for a group of six friends in minnesota, it's all about the fun.
>> what's your favorite part about these?
>> it's really an attitude. you know, you can't take yourself too seriously. it is a bad car and a bad boat and it tends to make people smile.
>> they only go about 60 miles per hour on land. seven in the water. but the amphicar has always been like something straight out of a spy movie .
>> do you feel like james bond ?
>> sometimes. it depends on what i'm wearing.
>> there is always a small moment of panic. but with propellers in the back and seals on the door, it's actually a pretty seaworthy ride, most of the time.
>> no breaks?
>> no breaks.
>> reporter: the quirky little cars can be tough to maintain. they're made of steel which means rust, a reason the amphicar never took off in mass production and now there's just one place to buy spare parts.
>> it drives like a truck.
>> reporter: there's no denying the 50-year-old cars can make anyone feel like a kid again.
>> if you own them, you will have the time of your life .
>> reporter: on the lake, or on the land. for today, nbc news, minnesota.
>>> i love the description. it's a bad car and a bad boat.
>> but looks like a lot of fun.
>> you have to call triple a. where are you? i'm in a lake.
