Growth of Mo Muscle Cars While many other restoration shops are closing their doors, MMC has been expanding, not only its shop size to 16, 000 square feet, but we now have 12 full time technicians in the mechanical and body shops. We insist on getting cars in and out with impeccable quality in a reasonable amount of time. We have had MANY customers who had their cars in shops for 3 years or more without any significant work done to them! Since we are all muscle car guys too, we know that having your car in the shop for a restoration or custom build is sometimes gut wrenching, especially after its there for a year or more. So, we have grown to meet the demand, and usually, complete jobs will take no longer than 6-8 months. This is quick when you consider that waiting on parts, sending back the wrong parts, waiting on chrome, upholstery, etc. cuts down our productive work on your car.
