When Hugh Hefner first asked out singer Barbi Benton, she
            supposedly said, "I've never been out with anyone over
            24." "Neither have I," Hef replied.
            
            We should all be so lucky.
            
            When it comes to cars, however, it's easier to get fired up over
            mature curves. Contemporary rides are obviously miles ahead in terms
            of power, handling, gas mileage, and technology. But they lack the
            intangible mojo that made these landmark vehicles timeless. Here are
            10 classic American cars that left a permanent mark on the
            automotive industry.
            
          
 
          
          
            Cool Fact: Red is the color we usually associate with the 'Vette,
            but in 1953, white was the only color offered.
            
          
          
          
            2 - 1955-1957 Chevrolets
            By the end of 1954, the Corvette was on financial shaky ground, but
            it still had style and showed promise. The same couldn't be said for
            the rest of Chevy's lineup, the members of which all looked much the
            same as the 1949 model and loped along on six cylinders. That all
            changed in 1955.
            
            Chevrolet's redesign was modern yet tasteful. The best part of it
            was the debut of the small-block V8. From there, the '56 got a nose
            job. And lightning struck a third time with the legendary '57. The
            tri-five cars each have their own unique look and loyal fans, but
            together they embody cruising like nothing else.
            
            Cool Fact: If the "regular" versions weren't
            exclusive enough for you, there was always the Chevy Nomad, a rare
            two-door wagon.
            
          
          
          
            3 - 1966 Ford GT40
            Who says that great things don't come from hard feelings? When talks
            broke down regarding Ford's prospective acquisition of Ferrari in
            the '60s, the Blue Oval guys became fixated on humbling Enzo at Le
            Mans. With the dedication of Carroll Shelby and his crew, they did
            just that with the GT40, beginning in 1966. This mid-engine car was
            equally brutal and beautiful, and the new Ford GT's lines look
            almost tame by comparison.
            
            Cool Fact: You gotta love the "Gurney Bubble," that
            little raised roof section first installed over the driver's seat to
            accommodate team racer Dan Gurney's height.
            
          
          
          
            4 - 1948 Tucker
            The Tucker is a great underdog story and an even better car. In the
            late 1940s, Preston Tucker decided to build a better car, and the
            Big Three took notice (some say they did more than take notice, but
            that's another discussion). Tucker clearly succeeded in his goal to
            develop a better, safer car. It rode on a four-wheel independent
            suspension. The innovative safety features continued inside with a
            padded dash and the "crash cowl," an area for the front
            passengers to duck into before an impending collision. Furthermore,
            a Cyclops-esque center headlight rotated with the front wheels.
            
            To the rear, the Tucker's horizontally-opposed six-cylinder pushed
            the car to an impressive 120 mph. Too bad Tucker's dream came to a
            halt after just 51 models had been built.
            
            Cool Fact: If you've seen Star Wars: Episode III -- Revenge
            of the Sith, you may notice that Senator Bail Organa's (Jimmy Smits)
            ride was inspired by the Tucker.
            
          
          
          
            5 - 1948-1986 Jeep CJ
            It's tougher than a car, more nimble than a truck, and it helped win
            World War II. How freaking cool is that? For decades, the Jeep CJ
            represented rugged individuality and a sense of adventure. It wasn't
            known for its speed, and even less so for comfort. But that wasn't
            the point. "It's a Jeep thing... you wouldn't understand,"
            as the saying goes.
            
            With the Jeep CJ, you could ditch the top and doors, fold the
            windshield and go for it. When you were done playing, you could hose
            the exterior and the interior. Try that with your Navigator.
            
            Cool Fact: Without Jeep, it's debatable whether or not SUVs
            would have ever caught on.
            
          
          
          
            6 - 1969 Dodge Daytona/1970 Plymouth Superbird
            Not many guys can claim their car was too hot for NASCAR, but you
            can if you own a Dodge Daytona or a Plymouth Superbird. They were
            even wilder than the original models form which they evolved -- the
            Charger and Road Runner. The Daytona and the Superbird could really
            fly, but their elongated snouts and sky-high rear wings kept them
            planted. No one really knew it at the time, but they were the apex
            of the muscle car era; and like that period, they were gone too soon
            after NASCAR rule changes made them obsolete.
            
            Cool Fact: Buddy Baker took his Daytona just over the 200-mph
            barrier at Talladega, a record that stood for 13 years.
            
          
          
          
            7 - 1964-1970 Ford Mustang
            We can forgive Lee Iacocca for the Mopar K-cars. He's the father of
            the Mustang. When it debuted in 1964, everybody -- really, everybody
            -- wanted one. Huge lines formed at dealers just to see one. Equally
            big lines formed to actually buy one. Dozens of options allowed the
            driver to equip it from mild to wild without breaking the bank.
            
            And it wasn't long before Carroll Shelby lent his magic touch to
            some truly special editions. Oh, and can you say Bullitt without
            thinking Mustang?
            
            Cool Fact: The earliest Mustangs, known as 1964 models,
            didn't have adjustable passenger seats.
            
          
          
          
            8 - 1964-1970 Pontiac GTO
            Years before he crafted Michael J. Fox's Back to the Future wheels,
            John DeLorean quietly created what many consider to be the first
            serious muscle car. It may have been a Tempest on steroids with a
            name lifted from Ferrari, but the GTO was like nothing else. Its
            looks alone made you think twice about trying to outgun it. If that
            didn't do it, the Goat's unruly horsepower would give you ample
            opportunity to check out the back end as it pulled further ahead of
            you.
            
            Cool Fact: The GTO clearly violated General Motors'
            restrictions on racing and power-to-weight ratios at the time of its
            development.
            
          
          
          
            9 - 1959 Cadillac
            Here's a car that can be described in just three words: tailfins,
            tailfins and tailfins. No doubt the resulting huge blind spots
            caused some VWs to be swatted aside during lane changes. Maybe
            that's why tailfins simmered down in the following years -- or maybe
            it was a secret Big Three treaty that was responsible. Whatever it
            was, this car marked the end of an era in automotive design.
            
            A gaudy way to go out? Sure. But today, it's a huge part of this
            car's timeless appeal. When you have a car as unapologetically big
            and bold as a '50s Caddy, why be modest?
            
            Cool Fact: If you can force yourself to quit staring at the
            tailfins, move your eyes a little lower. The '59 had another unique
            design element: The front grille design was mimicked in the rear.
            
          
          
          
            10 - 1949-1951 Mercury Coupe
            What other car looked like a chopped-top, lead sled straight from
            the factory? While the other guys' cars looked more liked
            warmed-over pre-war models, Mercury cut down the greenhouse and
            smoothed the sides of theirs. It's one of the earliest designs that
            gave the illusion of speed even while at a standstill. A few years
            later, its popularity grew even more when it becomes the ride of
            choice for James Dean in Rebel Without a Cause.
