It was worth every minute of the 8+ hours I drove to East Texas Muscle Cars! It's obvious that Stephen takes great pride in getting the most out of your car. I couldn't be happier with the outcome of my project. You're treated like a friend and I really appreciate that! He helped me with my rental car, hooked me up with exhaust that I needed and even offered to loan me his fishing gear!! Doesn't get any better than that. Great shop, Great prices, Great guy!!
