How do I add another car to my insurance policy?

I’ve wanted a convertible for some time. However, prices are a tad high, that is, until I found the Buick Cascada. My only issue is that I want to make sure it has high-quality standards. Where does Buick make the Cascada?

I’ve been looking at the reliability of different cars and there’s a lot of variation. I know many popular brands like Toyota and Lexus are reliable, but with only a few thousand produced each year, are luxury cars like Rolls Royce reliable?

I try to avoid being in the car at night whenever I can because it always makes me feel dizzy and nauseated. Why does driving at night make me feel sick? Is it eye strain or something else?
