Rich’s Diesel Performance LLC 7304 Talbot Run Road, Mount Airy, MD 21771

""Best in the business" by far... this guy knows vehicles fixed my truck in less than week and cost me 1/2 the price from any other dealership or local mechanic and filled my truck full of fuel when I picked it up... thanks rich!"

"Talk about professional... Rich is the definition of it. I can honestly not say enough about how excellent his quality of work is. He does everything 100 percent right. It has been very hard for me to find an honest mechanic that takes pride in their work. In the past I worked as a Diesel Mechanic and went to Trade School for Diesel Engine and Truck repair. so I am very cautious about who I let work on my trucks. and in the past I have done all the work myself, but lately I don't have the time to do the repairs because I own a Septic repair and Septic Service company. I heard about Rich from a few friends and a family member that have used his services. They all spoke very highly of Rich so I decided to give him a try. And Rich certainly exceeded my expectations. You can tell that Rich has a Passion for what he does and he will treat your truck like it is his truck. He is very honest about everything and he truly wants what is best for you and your truck."

"Rich does amazing work at a fair price. A real stand up and honest shop."

"I can’t say enough great things about Rich and the work he performs. I took my 2020 GMC 2500 to him after accidentally putting DEF in the fuel tank and running it. The job was massive. Rich communicated with me regularly and kept me informed of what was going on. He worked with my insurance company so I didn’t have to. I basically dropped off a trashed truck and he returned it to me in perfect working condition. Aside from all of that, he’s just a great guy who works hard doing something he is clearly passionate about."
