Sedans and smaller wheels are the kings of ride comfort

Lately, I've been rotating between a BMW 520i, a Mercedes E200, and a 10-year-old old Malibu, and surprisingly, the Malibu has the best ride comfort. It was so strange that I sat down and thought about it, and it turns out the Malibu has the smallest wheel size. 17 inches lol. I guess wheel size is very important for ride comfort.
