Mmi Concepts

Formerly known as Marshall Motors, we changed to MMI Concepts when we started to specialize in Volkswagen pre-owned vehicles, parts, service and performance. In 2000, MMI Concepts built a show-winning silver 1991 VR6 GTI. A year later, a bolt-on turbo kit was installed and the show car found a new home at the drag strip. The car made consistent pow... er and was a reliable street/strip vehicle. Finally, in 2003, the bolt-on turbo kit was replaced with a custom turbo set up. The engine registered 590 wheel horsepower on the dyno. The car ended up running a best of 10.84 seconds at 133 mph. At the same time, we started building Volkswagen conversions and turbo charged VW's. One of our shop VW's, a 1990 VW GTI, street car with a TO4 60-1 HiFi turns consistent 11's and is driven to the track. We have also built many Volkswagen show cars as well as street and strip cars. Presently our strong customer base is growing from the Lehigh Valley to the Reading and Harrisburg areas to western New Jersey and into New York. At MMI Concepts, our goal is to offer top quality vehicles, service and custom Volkswagen parts and performance. ©2021 MMI Concepts, Inc.Read More
