Recent Project

“I've had a lot of work done on custom vehicles in the past, and this is by far the best work that I've ever experienced. The crew at C4 is extremely precise and exceptionally knowledgeable about engines, chassis, exhaust systems and transmissions. They are able to adapt their winning background in NASCAR to apply performance and style to any vehicle.”

“Fantastic job. They located all components prior to my bringing the truck in. They refurbished and painted all used parts. They kept me updated on the progress and the problems they encountered. They made some other safety upgrades while the truck was in the shop. It was a very nice professional installation and the truck was ready when promised. I was very impressed with the installation and how quickly they made the conversion. The truck drives like a brand new vehicle.”

  • Dan P.

    Owner of CPA Accounting Firm

“I would like to thank "C4" for the tremendous job of restoring the 1935 Ford Patrol vehicle. The Colorado State Patrol 1935 Ford will be displayed at the Museum at the Colorado State Patrol Training Academy at Camp George West. A heartfelt thanks goes to the C4 Hot Rods & Complete Restoration for being a part of bringing the history of the Colorado State Patrol back to life.”
