American Restoration (2010)

S3E4 Mixed Signals

When a vintage 1920s "wig wag" train signal shows up, Rick and his team dive headfirst into its restoration. Will they manage to keep everything on schedule, or could things go awry? Meanwhile, Kelly organizes a car show at the shop, prompting Rick to issue a challenge to the crew: they must seek out the most impressive vehicle for a secret reward.
