After meeting with the president of the Iowa Speedway, Don and the guys are hired to create three different tailgating games for the track's 25,000 fans to use on race days. Each game needs to tie into automobile history, but the shop is short on vintage car parts. To find enough pieces to work with, Don and Hal gain access to an auto graveyard which features hundreds of rusting cars just parked in a forest. Once back at the shop, Don has trouble getting Rex and Brian to complete the custom builds in the tight, two-week timeframe the track has requested. Something that's not helping his cause is Hal, who wants a new, mid-century modern mailbox for his own home and has secretly moved his pet project up to the front of the line.
