Can I add my 22-year-old daughter to my car insurance?

As I’m car shopping and looking at all these features new cars are coming out with, I had this random memory pop up. Did I imagine it, or do minivans have swivel seats? Or at least had them at one point?

I want to get another key for my Honda to give to my girlfriend. What’s the best way to duplicate a car key?

I’m trying to budget to buy a new car. I’d like to figure out how much interest I’d be paying on my car loan so I can move things around. There’s a lot of calculators out there, but I’d rather do it by hand. I trust myself more than logging numbers into something online.
