Point: More and more automakers are installing large glass roof panels that can’t be opened. If I have a big sunroof letting light in, it makes me want fresh air, too. I’m a big moonroof fan, and initially liked the idea of these larger open roofs.But after living with several, I’ve found they’re usually too noisy to open on the highway and only really useful on back roads. Plus, if you don’t use the sunshade, they add a lot of heat in the cabin on sunny days, making the air conditioner work harder. Some of these panels-like on the Lincoln MKT and the Volkswagen Passat CC--don’t even open at all. I’d prefer automakers go back to offering smaller, normal, quiet moonroofs.

Counterpoint: I don’t like moonroofs. Sure, they can be an occasional novelty, but I much prefer a lower purchase price, more head room, and reduced risk of problems. Plus, I like a quiet cabin where I can enjoy music or the company of my traveling companions.
For me, the trend of fixed glass tops is welcomed. Exposing more of the outside world can be wonderful on a tree-lined road or even just during balmy weather with fluffy clouds in the sky by day and stars at night. In most vehicles so-equipped, fixed glass benefits the rear passengers, creating a more open cabin feel and enhancing their enjoyment.
