This Terrain replaced our 2011 Subaru Forester which was a nice car many years ago but is now a basic car with few safety features. They thought of everything with this Terrain! The Denali trim is the top-of-the-line Terrain model. It has many safety features and some features that aren’t essential but really nice for comfort like cooling seats, heated mirrors and steering wheel and even a front camera. Good on gas mileage. The body style is modern and sleek and I wanted an SUV with AWD. We’ll see how it drives in heavy snow but I’m sure it will be fine. We even got the color I wanted, charcoal gray. This is the nicest car I’ve ever owned! Even my “Clint Eastwood” Dirty Harry critical car buying husband loves it!

23,000 miles and tires are bald. Can't drive it over 50 without the car slipping with new tires. The screen has went out on me twice and it seems to not shift well when first taking off. I'm mostly disappointed in the way it handles on wet, icy and snow covered roads. The rear end sliding and it sways all over the road. If the wind is blowing it is awful. sucks
