For $4, today's Groupon gets you a ticket good for one day’s admission to the Tampa Bay International Auto Show produced by Motor Trend and held at the Tampa Convention Center, December 3–5 (up to a $9 value, depending on age).

The Tampa Bay International Auto Show features cars from the entire automotive spectrum—classics and new models from major manufacturers, concept cars from Corvette and SEMA, and iconic Hollywood autos like Back to the Future's time-traveling DeLorean. Toodle about in vehicles from Chevrolet, Buick, and GMC, or cheer on rubber duckies as they make their way down the Garrison Channel during the Lucky Ducky Derby.

Check the venue map to plan your visit. Kids 6 and under are always free, and children ages 7–12 enter free with paying adult on Sunday, December 5. Buy a Groupon for everyone and fuel your whole show with the better-for-the-environment Grouethanolpon.
