What should you actually do when your vehicle reaches 100,000 miles — keep driving it or trade it before something expensive breaks? In Episode 83 of the KillerGrowth Podcast, Samuel sits down with Mike Dorrell, founder and owner of Superior Auto Care, to talk about cars, entrepreneurship, customer service, and how dramatically the automotive industry has changed. Mike never planned on owning an auto repair shop. After working in aircraft and spending years with Safelite AutoGlass, he decided to take a risk and start his own business in 2015. Superior Auto Care began with just two bays, a tiny office, auto glass, and truck accessories. Then Mike’s dad — a mechanic for more than 50 years known as “Merlin the Magician” — retired and came to help three days a week. By the first week, he was already working Monday through Friday. Mechanical work took off, more technicians followed, and Superior eventually grew into the full-service operation it is today. Mike shares what he’s learned about scaling a service business, knowing when to expand, eliminating services that distract from what you do best, and why taking care of employees is critical to taking care of customers. Then they get into cars. Mike explains why modern vehicles are increasingly difficult to diagnose, which repairs can become nightmares, whether 100,000 miles should scare you, what brands he trusts, and why buying a different vehicle often just means buying a different set of problems. They also talk EVs, hybrids, expensive batteries, autonomous driving, and what the future could mean for independent repair shops.
