Auto shows are the safest places to practice pretend engine noises without attracting lawn mowers in heat. Rev up with today’s deal: for $7, you get one ticket for ages 7 and up to the Piston Power Show at the I-X Center (up to a $15 value). This deal is valid only for the show on Friday, September 30 from 3 p.m. to 9 p.m. Children six and younger receive free admission.

For the second year running, the Piston Power Show and Excalibur Auto Body fills 1,000,000 square feet with cars, motorcycles, trucks, and airplanes, as well as family-friendly activities and prizes, making it one of the largest indoor vehicle displays in the world. In the vehicle showcase, visitors stroll past more than 1,000 transportation contraptions, admiring the gleaming chrome of classic cars, a fully restored B-17, and a meet-and-greet with the tiny horses that pull the engine’s piston. New this year, the Ohio Bike Week Pavilion and Fall Show will showcase live music from bands including The Earthquakes and Thunderstruck, hot dogs, beer, and herds of rowdy motorcycles (food and drink not included with this deal). Parents can instill a love of speedy locomotion with interactive displays, simulators, the All-American Soap Box Derby boasting a 250-foot long Indoor Rally track for side-by-side racing, and a fun kids’ zone featuring famous cars from Transformers and Starsky and Hutch. A live band croons nostalgic tunes from the ’50s and ’60s to offset the atmosphere of fierce competition in Thunder Row, a collection of 32 show cars from around the country wooing judges with powerful engines and svelte figures in the swimsuit competition.
