Can’t say anything about Chicago (didn’t locate anything on the show website about test drives), but if you can make it instead to Oregon the Portland International Auto Show, January 26-29, 2017, as told on the portlandautoshow.com website:
"Chevrolet is back this year, including an exclusive all Bolt EV Ride and Drive on Friday, and a full line of Chevrolet vehicles including the Bolt EV on Thursday, Saturday and Sunday. Location: North end of the Convention Center at the Holladay show entrance, Thursday – Sunday 10:00am to 5:30pm."
Chevy has thanked me for driving my 2012 Volt by e-mailing me two free tickets to the show, urging me to come Friday and take a test drive.
