What Our Customers Say
Drew Lynch

"Excellent service by Hamza and his staff. The price I was quoted was the price I paid and was the lowest quote I got by about $100 dollars from 4 different shops. Dropped off my vehicle and the repair was done within 3-4 hours, albeit a simple repair but in my experience 3-4 hours on anything outside an oil change is note worthy. Definitely going to be my go to for vehicle servicing going forward, the standard pricing on the website is all more than fair."

"Benchmark and the owner Hamza are my family's pick for superior service, timely resolution and reasonable pricing. They are an honest, ethical, knowledgeable and hardworking group of workers. On a hot summer day, the lobby area is always nice and cool. They have complimentary coffee and last time I was there, they also had lemonade on ice. I've also referred a few people here and all have had a great experience. 5 out of 5 times, they have fixed the problem correctly on the first try. Thanks, Hamza and Benchmark. You have a loyal family of customers with us. See you soon but hopefully not too soon ;)"
