Why are my windshield wipers leaving streaks?

Over a glass of sherry the other night, I was lamenting the shifting state of domestic manufacturing. I’m certainly a fan of import vehicles (there’s a Prius in my garage), but I’m thinking about changing my image from a blazer-and-elbow patch-wearing, pipe-smoking professor to a cool, beer-chugging (not while driving), rugged professor—I’m certain this change will go splendidly. To burnish my new look—and to help the American worker—I’m thinking about buying a Jeep. Where are Jeep parts made?

I have a Hyundai Sonata and my mechanic said the spark plugs need to be replaced at my last oil change. I didn’t think it had been that long since they were last changed. How often do you need to change spark plugs in a Hyundai Sonata?

Do lenders look at both credit reports? My Equifax report is spotless, but my TransUnion score isn't nearly as good. I'm worried that they'll only look at the lesser score. I want to buy a car and I know that car dealers pull your credit.
