Established in 1987.

Greg's Car Care is a family owned business serving auto repair and auto body customers in the Weldon Springs, St. Charles, St. Peters and O'Fallon areas for over 20 years. When you come to us, you get the most skilled technicians, the best parts and a sensible approach to auto repair and maintenance.

In 2001, we built our current location. It is a 14,000 square foot facility with separate areas for the mechanical bays and body shop.

We have a state of the art paint system and are one of the few shops in the state to use the latest in waterborne paint technology. Waterborne paint has become the standard used by car manufacturers, but Missouri has not passed a law to require its use in body shops. By making the voluntary switch to waterborne paint, we are doing our part to help the environment by improving air quality and reducing the health risk to all involved.
