Because it required far less expertise than the typical hot-air balloon and far less human blood than the typical horse, the motorcar completely revolutionized American transportation and culture. Today’s Groupon gives you a sneak preview of the automobile’s latest evolutions. For $5, you get a one-day adult admission (a $10 value) to the Long Island Auto Show, produced by IAS in association with Motor Trend Auto Shows. The show takes place October 15–17 at the Nassau Veterans Memorial Coliseum.

One of the nation's largest auto show producers, Motor Trend dazzles 24 markets throughout the country with the latest breeds of horseless carriages and steel steeds in all their glittering glory. Each show boasts its own parade of the latest models, all of which are unlocked and waiting to be admired inside and out. If the sleek, muscular sports cars from Ferrari and Maserati remind you too much of your old job as a secret agent valet, you can also shop for future cars among the more practical permutations of Suburu, Kia, and Buick. Fans of good old-fashioned American size and power, meanwhile, can make themselves look tiny by standing next to the 2011 Ford Super Duty.

An auto-bazaar's worth of vendors and exhibitors will also be on hand to talk shop and make vroom-vroom noises with fellow gear-heads. Unlike the country of Luxembourg, you can't see it all in one day, so purchase multiple Groupons to attend on multiple dates.
