CS Automotive of Tennessee has been acquired by Left Lane Auto.

A family-owned business, CS Automotive has been part of the Brentwood, Tennessee community for nearly 20 years. Since opening in 2006, Rob and Kim Auernheimer have grown from a single bay in a warehouse to a thriving 10-bay shop—and expanded with a second location in Monteagle in 2023.

A statement from Left Lane said, “Their commitment to exceptional service and building trust within the community has made them a go-to for drivers across the region—and we’re excited to carry that legacy forward. With CS Automotive joining the team, we’re now proud to have 87 shops in the Left Lane Auto family.”

Left Lane Auto is based in Champaign, Illinois and recently acquired Don Foshay’s Discount Tire and Alignment in Maine. Last year, Left Lane acquired 30 locations in 2025.
