Affinity Automotive Services mechanics in Wichita

Get to Know Our Wichita Auto Repair Shop


Affinity Automotive Services, started in a garage after hours—in fact, our name used to be After Hours Auto Repair! But, in 2009, we changed to normal business hours, and over the years, our customers suggested we should change our name to reflect who we are today. Well, a big part of our business is listening to our customers! So, that’s what we did, and we officially became Affinity Automotive Services in 2018.

Why Affinity, You Ask?


The definition of “affinity” is a natural liking or caring for someone or something. This word summed it up for our customers, and through surveys a decision was made. Thank you, Wichita, for all your ideas and support over the years. We will continue to provide the best auto repair service in the Wichita area because of every one of you!

A Family-Owned Auto Repair Shop Dedicated to Quality & Service


Since 2008, Affinity Automotive Services has been giving the people of Wichita an auto repair shop they can depend on for honest car care advice and top-notch customer service. We are proud that many of our customers come to us through word of mouth because our reputation is built on honesty and dependability. As an auto repair shop, we love that we can help people, cheer them through life, and make sure our customers’ vehicles are in the best shape to meet their needs and achieve their goals. We also love getting to know other independent auto repair shop owners, so we can share stories and experiences.

    Mark Guerrero IIOwner & Master ASE-Certified Technician

    My passion started earlier in life for cars, motorcycles or anything that had a motor and wheels, I grew up around all of them and started working on everything at the age of 14 but it really started with my 1st car a 71 Nova (which I still have today). I quickly learned that you cannot not just rip something apart before knowing the specifics on putting it back together "correctly" this knowledge came from my parents and friends of my parents that were in the industry and nothing really peaked my interest or gave me more satisfaction than cars, motorcycles, and the accomplishment from having something that doesn't run, turn into something that does. I only dreamed of owning my own shop one day. Summer always told me "it will happen one day, we just have to work towards it." So I worked in the dealerships and would take notes as to how I could make the customers experience better or the things I felt was missing for the technicians. After working in the industry for over 12 yrs, we had consulted with professionals and prepared to open a shop. March 2008 the doors to After Hours Auto Repair opened. I couldn't be any happier with how we have grown, the customers we have met and got to know and building a team to accommodate to our customers needs and wants. I believe that continued training is extremely important, to keep up with the quickly evolving technology in this industry and with the consumer. 2018 we decided to change the name of the company. Our customers are a large part of our decisions in the growth of the company. When they speak, we listen. Our services changed for the demand of our customers and the name just wasn't as fitting as Affinity - definition a natural liking or caring for someone or something . Now we have a name that is suitable for any growth in the future.

    Mark and I have been together since we were 16 years old, seeing his passion in helping people and gift of diagnosing and training others to repair a vehicle made me want to make a difference in the automotive industry. I am a Army Iraq War Veteran, and served as a fire fighter for 15 years. I enjoy building relationships and finding out how I can help our customers either by educating them about their cars or by giving recommendations of others whom we trust in the industry to help them if we can't. When you walk into our shop you will feel welcome and at home in the family atmosphere we provide. I also enjoy public speaking about passed experiences both personal and business and working with young entrepreneurs, to help build our country's future.
