Can I refinance my car loan with a different bank?

So I have this quirky neighbor who tells me all sorts of interesting (and frankly, outlandish) things about all sorts of stuff, including cars. He seems to have a thing for Nissans, and he told me that an early prototype of the new GT-R was sitting… in his garage. Now, when I asked to see this prototype, he got all flustered, saying his garage door opener broke, and then scurried away, muttering something about needing to sell a bunch of used trucks. I’m pretty sure this guy doesn’t even work for Nissan. Anyways, where is the Nissan GT-R made (for real)?

I’ve been having trouble starting my 2006 Buick Lucerne, and a friend suggested I look at the battery terminals to see if they’re corroded. I popped the hood, but nothing looked like a battery. Is the battery in a Buick Lucerne located somewhere besides under the hood?

Although the new car warranty from Fiat is better than many of the other options, I still want to get an extended warranty for some added protection—provided it’s worth the price. What does the extended warranty from Fiat cover?
