Season 6

On the surface, an iconic '57 Chevy looks great, but after a test ride and inspection, the guys discover that looks can be deceiving. A couple's '41 International project is nine years in the making before Joe steps in to save the car and the marriage.

Custom car guru Joe Martin is putting the finishing touches on a big-block '57 Bel Air, getting ready to reveal the car to its owner. Joe also uses all his tricks to transform an old C10 Chevy hood into a stylishly painted, charity auction record setter.

It's beginning to look a lot like Christmas as Joe and his crew tackle a unique request -- turn a salvaged red '51 Chevy 3100 pickup into a roadworthy, Christmas-parade spectacle. Joe devises a plan for bigger power, an updated suspension and more.

With a ton of elbow grease and a little help from Santa, custom car guru Joe Martin and his team at Martin Bros. Customs put the final touches on the transformation of a red '51 Chevy 3100 pickup into the dazzling Christmas-parade truck it was born to be.

Joe dusts off his prized '65 Pontiac Catalina to give it the facelift it deserves -- new brakes, a new trick frame and a bigger, badder LSA 600 horsepower motor. Meanwhile, Martin Bros. Customs tricks out the interior on an iconic 1932 Ford Roadster.

Part 2 of Joe and his prized '65 Pontiac Catalina to give it the facelift it deserves -- new brakes, a new trick frame and a bigger, badder LSA 600 horsepower motor. Meanwhile, Martin Bros. Customs tricks out the interior on an iconic 1932 Ford Roadster.

A longtime customer has his eye set on a car from Joe's personal collection, a 1967 Nova. Joe counters by offering up a 1966 Nova, with the guarantee that it will be twice the car Joe's is. That means big brakes, big power, big wheels and more.

Joe pulls out all the stops to make the '66 Nova the car of his client's dreams. Joe doesn't just want a mean motor and big tires. He wants a chopped roof, but the car might be too far behind schedule for a chop, even if it does up the cool factor.

A customer from New York entrusts Martin Bros. with his prized 1965 Buick Riviera, and when it's done, it won't be his father's Buick anymore. Joe wants to update the car with crisp body lines, a trick paint job, a 525-horsepower LS3 and more.

Joe and the crew button up the 1965 Riviera's wiring, interior and paint before the owner arrives from New York to reclaim his car. With the finish line in sight, a wrench gets thrown in their plans when the paint job needs to be taken out of house.
