If your knowledge of car repair and maintenance is limited to phoning AAA to jump-start your battery, flagging down someone to change your flat, and drive-through oil changes, this weekend you have the chance to become empowered. Lauren Fix, host of Do-It-Yourself Network's "Talk 2 DIY Automotive," and more impressively, a guest on the "Oprah" show, comes to Rochester this week to promote her third book on cars.

"Lauren Fix's Guide to Loving Your Car: Everything You Need to Know to Take Charge of Your Car and Get On With Your Life" offers straight-forward advise on caring for your car and enjoying your ride. Fix will be at Barnes and Noble Greece, 330 Greece Ridge Center Drive, on Wednesday, July 23, at 7 p.m. to sign copies. Call the store at 227-4020 or visit barnesandnoble.com.
