2026 BMW Z4
Why Buy From Grayson BMW?

M Certified Center: Access to the Rare.
The 2026 Z4 M40i is a specialized machine, and availability for the Final Edition will be strictly limited. As an authorized BMW M Certified Center, Grayson BMW receives priority access to M products and special editions.
This certification is earned, not bought. It signifies that our client advisors and technicians undergo rigorous, annual training led by top M Brand experts. When you build your Z4 with the "Handschalter" package, you are working with a team that understands the mechanical nuances of the 6-speed linkage and the revised M differential. We speak the language of performance because we are enthusiasts ourselves.
The Grayson Advantage: Service Loaners for Life.
We believe that maintaining your Z4 should never disrupt your life. That is why we offer Loaner Cars for Life with scheduled service appointments. Whether you are in for a break-in service or a major interval, you can continue your day in a premium BMW loaner vehicle while our technicians care for yours.
Our service commitment goes beyond convenience.
- Video Walk-Arounds: Our technicians send detailed video updates of your vehicle inspection directly to your phone, ensuring total transparency before any work begins.
- Factory Training: Our team includes technicians who specialize in high-performance BMW models, ensuring your B58 engine and manual transmission are serviced to factory specifications.
Deep Roots in the Knoxville Community.
When you buy from Grayson, you are investing in a local business that reinvests in the community. We are proud to be "more than just a carmaker" but an active neighbor in the Tennessee Valley.
Our partnerships reflect our values:
- Young-Williams Animal Center: We actively support animal welfare initiatives to ensure our four-legged neighbors are cared for.
- Knox Pride: Grayson BMW is a dedicated sponsor of Knox Pride, supporting vocational suites and promoting a diverse, inclusive community.
- Education & Environment: From supporting STEM education to partnering with local environmental projects, we are committed to building a sustainable future for Knoxville.
Executive Demos: A Smart Path to Ownership.
For drivers seeking value without compromise, our Executive Demo and Service Loaner inventory offers a unique opportunity. These are current-model-year vehicles driven briefly by our management team or used as service courtesies.
- Like-New Condition: These vehicles have low mileage and have been meticulously maintained by our own service department.
- Financial Advantage: Because they have been previously titled to the dealership, they often come with significant price advantages while still qualifying for new vehicle programs and the balance of the Ultimate Care maintenance plan.
