Data overload due to buying a new vehicle

I feel like I'm on "data" overload. I've been calling insurance companies getting a quote on insuring my used vehicle. After two companies and a wonderful quote, I think I'm done. I felt a little dumb, when I needed the insurance agent to explain what the words "lean holder" meant. Luckily, she was really nice about it. I just want to get through this whole car buying process as quickly as possible!
