All of these are nitpicky, considering I recently purchased a CX-5 [2016.5 Sport] after looking at CR-Vs, RAV4s, Foresters, and Escapes, but...
I wish the visibility to the rear of the cabin was as good as the Forester, though the tradeoff is making the vehicle less attractive.
I wish the backup camera adjusted its guidelines to include how you are turning, like some Fords.
The speedometer should have every 10 mph indicated, rather than every 20.
The rearview mirror flips the opposite way from what I'm used to -- my old car would have you pull the lever forward to block headlight glare, rather than push.
The manual height adjustment for the driver's seat is odd, but at least I only need to set it once.
Didn't care for the carpet -- it's hard to believe how much stuff it picks up -- so I bought floorliners front and back.
Like I said, pretty nitpicky. I'm on week three of my new ride, though, and I really like it!
