About Affinity Automotive Services

A Dream Built on Honesty, Forged by Purpose

Mark and Summer Guerrero have been together since they were 15 years old, united by Mark’s dream to own an automotive repair shop that would prove that good, honest technicians exist. While Mark honed his skills at dealerships, Summer became a firefighter, joined the Army, and deployed to Iraq. After returning and battling stage 4 breast cancer, one thing became clear: the purpose they were meant to fulfill together was still waiting.

In March 2008, Affinity Automotive Services opened its doors in Wichita, KS. Mark brought technical expertise. Summer brought business strategy and customer communication. Together, they built a shop that truly cares about the people who walk through the door.

Our Mission

Our mission is to raise the industry standards by providing excellent customer service, educating the customer to make good decisions on their vehicle repairs, and providing accurate and quality workmanship on all repairs and services.

Your Family Depends on Your Car.We Treat It That Way.

At Affinity Automotive Services, every vehicle is looked over as though it belongs to a family member. Our technicians take pride in resolving your concerns, and every vehicle goes through quality control to make sure the problem is actually fixed so you are not coming back for the same issue.

We understand that not everyone can afford to fix everything at once. That is why we customize every report specifically for your vehicle and work with you to build a plan. We help you prioritize what may be unsafe or unreliable, putting the power back in your hands to make informed, confident decisions. You are treated like a person here, not a ticket number.

Summer has a personal mission that shapes the way the shop communicates with every customer: to help women and moms feel confident and educated enough to make the right choices without fear of being taken advantage of.
