Ayers is awesome. Perhaps a tad more pricey than other big-box shops, but you really get what you pay for. They're locally owned and are not only Green Business Certified (meaning the operate in an environmentally friendly way, from preventing pollution to conserving energy and water), they helped create the Green Biz automotive checklist! Great customer service and if you stick with them, they actually recognize you and help you stay on track with your vehicle maintenance in a non-threatening, honest and friendly way.
