The 4 most American cars you can buy in time for our nation's birthday

Just so you know, whittling this list down to four was damn near impossible. So many iconic monsters scream America, but not all of them have the most "American" stories to back it up. We took the time to scrape the eBay barrel for the four most impressive examples of American might, ingenuity, and stubbornness. Go ahead, disagree with us: it's a free country.

1972 Oldsmobile 442 W-30 $89,000:Leading up to the 1973 oil crisis American auto manufacturers started to see the writing on the wall: gas was going up, insurance was skyrocketing, and their cars were averaging less than 10 miles per gallon. Just two years prior the Olds 455 V8 was the standard engine in the 422. In 1972, that was far from the case, being mitigated to an exclusive trim package that was frequently advised against by gas price conscious dealers. That didn't stop this dude from tracking down a dealer that would order the "W-30" option, maintaining the L77 455 Engine and a slew of other performance parts that completely scoffed at the notion of skyrocketing gas prices. Let us pause for a minute to acknowledge just how American that is.

1970 Ford Mustang Boss Snake $159,000: It's undisputed that 1970 was the pinnacle for American auto manufacturing, and coming off the 1969 Nascar season, Ford was on top of (most) of the racing world. The Trans Am circuit was another story however, which is when Ford exec Bunkie Knudson (yeah that's actually his name) came up with the idea to build two prototypes of the Mustang Boss designed to dominate. When Bunkie was laid off later that year, these prototypes never saw the road, instead becoming Mustang legend. Fast forward 40 years, and some whacked out Ford fanatic set out to finally create their version of a road legal 1970 Boss Mustang, bolting a 6 speed on to a John Case 529 HEMI Boss Nine engine outputting 770 horsepower and 720lb./ft. of torque. F*ck yeah, America.

1970 Buick Skylark GSX Stage 1 $160,000: The GSX was Buick's answer to the Pontiac GTO Judge and Oldsmobile's 442 W-30. Originally advertised as "Another Light Your (Ass) On Fire Car From Buick", it was only available with the soul crushingly powerful 455 engine, with a total of 400 cars being outfitted with the optional Stage 1 performance package, aka "The Hemi Killer". What's more American than trying to crush your opponents using raw power? Nothing.

1966 Ford GT40 MK 1 $109,000: In the spring of 1963, Henry Ford II was sick and tired of not having a car to compete in the legendary French endurance race "Le Mans", so he flat out tried to buy Ferrari. He plowed millions into a full on audit of the Italian powerhouse, only to have Enzo Ferrari kick him out of the factory after a disagreement over Formula 1 racing oversight -- Enzo it turned out wouldn't let Henry touch the race track, subsequently cutting off the deal to spite the American auto magnate's hubris. So what's a boy to do when he's been punched in the nose? Hit back. Hard. Ford ordered his racing division to destroy Ferrari in the most public way possible and from 1966 to 1969 the Ford GT40 won 4 consecutive overall victories at Le Mans, leaving Ferrari in the dust.Don't mess with America.
