D Mark Performance 2436 East Oakton Street, Arlington Heights, IL 60005

"Called with some questions about my 2016 f150. Very knowledgeable and willing to offer me advice. I would not hesitate to use D mark performance in the future."

"I purchased a '16 gt350 with a turbo kit already installed. It did not run well at all. Drew went through the entire car, we made some changes, and it came back a new car. Drew does excellent work and is highly recommended."

"My 2019 gt350 spent most of the summer bouncing from shop to shop. One Ford dealer quoted 2500$ in repairs that needed to be done. Thankfully I found Drew at D Mark Performance. He took a short test drive around the block and knew right away the repair job I was quoted was incorrect. He took apart the suspension, checked everything properly, even found an issue with the exhaust that no one noticed and corrected it. Drew is who you want working on your mustang, his attention to detail is unparalleled."

"I highly recommend Drew to work on your Mustang. He lowered my 2019 Mustang GT. Did an excellent job as usual. He worked on my 2004 Mustang GT in 2014 by lowering and exhaust work. Also did a great job back then. I drive one hour to get to Drew's workshop and had been well worth it. He even pointed out flaws that my car had. I highly recommend Drew to work on your cars."

"Went to see Drew about getting some upgrades on my mustang, he is very knowledgeable,takes the time to help you also understand what's a good idea or something that's not. As any good shop he's busy but took the time to respond to calls and emails. Did many upgrades, suspension, exhaust, headers,clutch and flywheel, supercharger upgrades, cooling system and tune. Very happy with everything, he was very reasonable on price, the install of everything was on time, the work was clean, very professional. The car has no issues, fast and fun. If you guys are looking for a good Performance shop for Mustangs I recommend seeing Drew."
