Produced by Motor Trend, the Nashville International Auto Show greets car lovers with an array of automotive attractions that highlight the most popular new rides and exotic vehicles. Visitors grip wheels, shift into gear, and test-drive the latest Scion land vessels, including the xB and tC models. Preproduction-model displays showcase the next step in vehicular advancements by rolling out autos such as the 2013 Ford Taurus. Exotic-car displays treat eyes to up-close peeks at some of the world’s most coveted steel steeds, and the 40+ MPG Club shows off an array of highly fuel-efficient vehicles—both hybrid and nonhybrid. Guests can also witness the finals of the Noshville Delicatessen hot dog–eating competition on Saturday and register for a chance to grab a moneybag inside a Land Rover Evoque, which may contain up to $25,000 in cash or Waldo’s lost scroll.

Families can coordinate their visit to overlap with Kids’ Day on November 27, which admits children younger than 12 free with a paying adult. Santa Claus will be at the Ford display from noon to 4 p.m. each day, posing for photos and Etch A Sketch portraits with youngsters. Admission to the auto show is normally free for children aged 6 and younger, $4 for kids aged 7–12, and $5 for senior citizens 62+.
