<div class="col-xs-12">Every inch, every detail, and over 125 components are rigorously inspected by Audi trained technicians to ensure each Audi Certified pre-owned vehicle is in optimal condition.Only after this exhaustive dealer inspection are we confident in backing the vehicle with our Audi Certified pre-owned Limited Warranty.The Audi Certified pre-owned Limited Warranty is extremely comprehensive; however, it is not an extension of the original 4-year/50,000-mile Audi New Vehicle Limited Warranty. The Audi Certified pre-owned Limited Warranty is only effective when the Audi New Vehicle Limited Warranty expires, and the coverage it provides is different from the New Vehicle Limited Warranty.If coverage remains under the Audi New Vehicle Limited Warranty (4 years/50,000 miles, whichever comes first) at the time of purchase, the New Vehicle Limited Warranty continues to provide coverage until its expiration.If there is no remaining Audi New Vehicle Limited Warranty coverage at the time of purchase, the Audi Certified pre-owned Limited Warranty coverage period begins immediately and continues for one year or 20,000 miles.</div>

Used Audi A6 for Sale in Killeen, TX - Autotrader

The description of “midsize luxury sedan” doesn’t do the Audi A6 any kind of justice. There’s no such thing as a perfect machine, but the A6 gets close. Spacious, refined, capable, composed, and comfortable, with high-class materials and an emphasis on design flair (inside and out), the A6 remains desirable even in the face of intense competition from BMW and Mercedes-Benz. Evolving throughout several generations, Audi builds the A6 with front-wheel drive or an optional <a href="https://www.autotrader.com/cars-for-sale/awd-4wd/audi/a6" target="_blank">all-wheel drive</a> system while offering engines that start with a perfectly fine turbocharged 4-cylinder unit. Some of the more popular A6 trims include the <a href="https://www.autotrader.com/cars-for-sale/audi/a6/2-0t-premium" target="_blank">2.0T Premium</a>, <a href="https://www.autotrader.com/cars-for-sale/audi/a6/2-0t-premium-plus" target="_blank">2.0T Premium Plus</a>, <a href="https://www.autotrader.com/cars-for-sale/audi/a6/3-0t-premium" target="_blank">3.0T Premium</a>, <a href="https://www.autotrader.com/cars-for-sale/audi/a6/3-0t-prestige" target="_blank">3.0T Prestige</a>, and <a href="https://www.autotrader.com/cars-for-sale/audi/a6/premium-plus" target="_blank">Premium Plus</a>.
