Grech Motors

Grech RV has set a new standard by defining what a Class B motorhome should be.

 

Grech Motors is the luxury ground transportation industry’s leading mini-coach manufacturer specializing in the highest quality mid-size buses and Mercedes-Benz Sprinter vans. Grech Motors products have set the standard for the ground transportation industry by defining what a mini-coach should be. With an unwavering focus on innovation, trend-setting designs, elegant style, curb appeal, unrivaled quality, superior fit and finish, an exclusive level of standard equipment, and the industry’s absolute best warranty and after-sale support.

 

Over thirty-seven years ago, entrepreneur Ed Grech made the ground transportation industry his home. Easily recognized as one of its leading innovators and visionaries as the founder and driving force behind what was the most iconic manufacturer for 37+ years, many wondered what would be next for this pioneer. The answer was Grech Motors, and what he has created will surely reinforce why his name has always been ­synonymous with quality and luxury.

 

“My philosophy in business is very basic,” says Grech. “I have always focused on delivering the highest quality products and providing unparalleled after-sale support. We stood behind all of our products and warranties. I have always taken care of my customers, and in return, they have always taken care of me.”

 

Grech’s history of entrepreneurship goes back to when he opened his first body shop in 1982. One day, he joked with his employees about cutting a car in half and stretching it into a limousine, only to find that exact vehicle cut in half when he returned from lunch. Thirty-Seven years and 35,000 vehicles later, his legacy is cemented in luxury ground transportation industry history. He’s among those who championed change; set standards in manufacturing excellence, customer service, and vehicle offerings; and indeed raised the bar in quality and safety.
