Free for most issues — we plug in, pull codes, and walk you through findings. Complex driveability or electrical diagnostics requiring 1+ hours of test time are $145/hr (waived if you authorize the repair). We tell you up front before any billable diagnostic time starts. ### Are you cheaper than the dealer? Almost always — typically 25–40% less on the same job because dealers run higher overhead and labor rates. Our parts are OEM-equivalent or genuine OEM (your call), our labor rates are independent-shop rates, and our warranty matches or exceeds the dealer's. ### Will doing maintenance with you void my warranty? No — federal Magnuson-Moss Act protects independent service. We document everything (oil weight, parts numbers, mileage) so your manufacturer warranty stays valid. Bring us the maintenance schedule and we'll follow it exactly. ### How long do repairs take? Oil change: 30 minutes. Brakes (pads + rotors): half-day. Major repairs (timing belt, head gasket, transmission): 1–3 days. We give you a written estimate with a realistic timeline before we start, and we call you with updates if anything changes. ### Do you do Missouri state inspections? Yes — we're a licensed Missouri state inspection station. Standard safety inspection: $12 (state-set fee). If something fails, we walk you through what failed, what the repair costs, and whether you're better off fixing it or applying for a temporary permit. ## Contact - Phone: +13145550182 - Email: service@libertyauto.example - Address: 5840 Hampton Ave, St. Louis, MO, 63109 - Service area: St. Louis · Webster Groves · Kirkwood · Maplewood · Clayton · Brentwood · St. Charles · Affton - Website: https://www.fastdigitalmarketing.com/examples/auto-repair _This page is structured for AI answer engines.
