This '67 Camaro full restoration is now complete! Though definitely a ton of work, the outcome was worth it! Be sure to take a few minutes to go through the entire album to see this amazing transformation! Shout out to our team, especially Scott, who spent countless hours of dedication to this project from start to finish in every aspect. 🤩We want to thank Andy for his business and being such an awesome person to collaborate with on this build!
