It's not that they don't belong on a car site, we have multiple people here who would not be considered enthusiasts, they come for questions or other things. The thing is the average car buyer views their car as an appliance and cares mostly about value and durability. Brands like Honda and Toyota are well established in that regard. Mazda has to shed the past of rusty Mazda3s and association with Ford to people who don't know that anything has changed.
The other issue is the move up market. Yes the interior of the CX-5 is very nice when loaded up with all the stitching and stuff, more so than a RAV4, Equinox, Tiguan, etc, but I think the top end CR-Vs are not bad, the new Forester is nice, and even some top end trims of the Sportage are very nice inside. I sat in a mid level trim of the new Escape and it was also well put together. Things that used to make the CX-5 a stand out only a few years ago like standard LED headlights which were only available on top trims of the competitors are now standard on them, such as a the CR-V, RAV4, and Subaru. When I bought my 2018 I thought it was the best deal in the segment. Navigation, LED headlights, Blind Spot, Leather, Premium Stero, all for about $31k sticker at the time. Now the competitors have caught up on value, an EX-L CR-V is $31k and is faster than the 2.5L NA in the CX-5. The average compact SUV shopper isn't going to want to spend the $40k on a loaded Signature. And while you'll steal some sales from the Lexus/Acura crowd, a lot of the people shopping the premium brands want a premium badge. It's the same conundrum for Genesis or those fancy Kia K900s. Yes they are loaded up just as nice as an S class or A8, but at the end of the day they are not a premium brand.
And when the average person who views their car as an appliance cross shops a Mazda the CX-5 loses out on things that matter to them like practicality. The competitors have more storage bin space up front, more usable second row space, and bigger cargo areas with lower lift over heights. Throw in better fuel economy in the competitors, especially when looking at the hybrid variants, and it makes Mazda the emotional choice. And most consumers don't buy their cars purely on emotion.
