Our Team

Jay Soneff was raised in a family that appreciated the automobile. Born and raised a Hudson lover because of their evolutionary styling and great performance, Jay grew up in the eve of the muscle car era hanging out at Bandimere Speedway for Friday night Drags and on 16th Street Downtown for Saturday night cruise. Working side by side with his father, the late John Soneff, Soneff's Master Garage, Inc. was voted Best Muscle Car Dealer by Westword Magazine in the 90's as the Garage had a great variety of Hemi and Six Pack Cars, Cobras, Vettes, Shelby's and Hurst Performance Series Cars. At just 16 Jay rebuilt his own Engines with the last one being a 426 Hemi in a 1968 Hemi GTX Convertible. Of course the re-build was supervised by another Late and Great Gene Hopkins who was at one Time one of Ford Motors top performance guru. It was said by many people back in the day that "nobody could get more horses out of a muscle car than Gene!" The Philosophy at Soneff's has always been to enjoy one's car. SMG has NEVER been a place that was branded as a keeper of Art pieces and builder of Concourse Winners. Cars were made to be driven, frequently washed, polished and have their hoods popped open at car gatherings. Cars were not to be permanent, stored in place "Art Pieces".
