How can I find really cheap car insurance?

I’m buying a second house—it’s a double-wide mobile home—down south, where I plan to live for half the year. However, my friend told me I shouldn’t do it because I won’t be able to insure a mobile home. Does a reputable insurance company like Amica insure mobile homes?

I'm a non-permanent resident who's in the U.S. for work purposes. I'd like to buy a car so I can get around more easily. Would I qualify for a loan?

I cosigned a car loan for my then-boyfriend two years ago and I've made all the payments. After our breakup, I asked him to give the car to me but he refused. Is there a way for me to get the car in my name only?
