The web can be an excellent resource when it comes to finding reliable medical information and buying a car ... if you know where to look! AOL's consumer advisor Regina Lewis shares her tips for making the most of your time online.

Revolutionhealth.com: If you're dreading a trip to the doctor's office and have undiagnosed symptoms, consider doing some research on a site like Revolutionhealth.com. It offers a simple diagnosis tracker where you can plug in your symptoms and find out a possible cause. Not only will you feel empowered by having information, but you'll also have a more efficient visit to the doctor because you'll be a more informed patient.

Automart.com. A car is the second biggest purchase for most people after buying a house, and negotiating at the dealership can prove to be an anxious experience. "Women -- every survey says -- pretty much dread it," Regina says. "So many choices, so many prices points, where's a girl to begin? The Internet." On Automart.com you can research different models, contact dealers and start to negotiate without leaving your house. Once you have something in mind you can find out about deals for your specific zip code. "Rebates and promotions vary regionally, so a little tip: Maybe type in a couple of zip codes. It could be worth the drive."
