Ryan and his WCC crew forge a place in automotive history when they team up with living legend Carroll Shelby to build a one-of-a-kind Mustang. Then Ryan's 10-year-old son doubles the shop's workload when he not only makes his first sale, but helps plan the customization as well.

Matters aren't helped either, when Derrick's poor job performance leads to legal troubles for WCC.

The Stormer build proves more difficult than anticipated and the tension is high when representatives of the Dubai royal family visit the shop to check on it. With the deadline rapidly approaching, Ryan nearly loses faith, but his crew shifts into overdrive and pulls an all-nighter to get the job done.

After customizing cars for celebrities and the super-wealthy, Ryan decides to give back to a worthy cause. He comes up with an idea to build the "Ultimate Contractor's Truck" for Habitat for Humanity, an organization that supplies affordable housing to those in need.

She wants Ryan to customize her older model Chevy Camaro to give as a present to her boyfriend's son for a graduation gift.

Ryan has built many cars for Shaq in the past, and now it's time to take it to the next level to win back Shaq's business. Ryan and his crew come up with an idea for a super-customized Cadillac DTS appropriately named "The Shaquillac."
