Sorry, but the Envision is classified as average or mediocre by several journalists. U.S. News made a consensus of many Buick Envision reviews online and wrote, "The 2017 Buick Envision ranks 12 out of 15 Luxury Compact SUVs. The 2017 Buick Envision gets lost near the back of the luxury compact SUV pack. It's comfortable to drive and nicely equipped, and it offers good value for the money, but in a sea of over-achievers, the Envision is just average." On Car & Driver, the Buick Envision is ranked #18 out of 19 Luxury compact crossovers/SUVs, 3 out of 5 stars. It's a cheaper option, but even small mainstream SUVs get better ratings and are more well-recieved.
First option is the 2018 Kia Sorento SX with Advanced Tech Package. I drove one on a short road trip and came away thinking it could be a luxury SUV. The leather, ride, road noise, seat comfort for the front and rear, and the technology are next to Lexus quality. Reliability is also a standout and it has a 10 year/100,000 mile warranty. It seems to be an underrated car because the Highlander and Pilot get all the sales, but the overall feel of this car is superior to most of it's competition. The second row seats are comfortable and spacious, but the third row is almost unusable, so just leave the third row down and use it for the trunk. It's also tough to see out the back, but all the safety features come with the tech package. Also, this is way more expensive than a small SUV like the two below.
An equally good, more fuel-efficient choice is the 2017 Honda CR-V Touring. It has an optimal driving position like most Hondas, is spacious, comfortable, fun to drive, quiet, and safe. Going with the CR-V means you'll have more than $6k left over and still have a very nice car. Plus, lower insurance costs and high reliability.
The Mazda CX-5 Grand Touring with Premium Package ties for best small SUV with the CR-V. It gives you an extremely upscale interior for a fraction of the cost of the luxury SUVs. Add to that a smooth ride and more than $5k left over and you have a compelling package. It's the best looking SUV on the market in my opinion. It's reliable, too. It's more fun to drive than many luxury CUVs. It's one of the quietest SUVs in the segment. Like all three of these SUVs, the rear visibility is compromised by the styling.
A lot of luxury brands are producing compact SUVs that are not as smooth-riding or comfortable as the mainstream brands' small SUVs. Compare the Honda CR-V to the Lexus NX and you'll see what I mean. There are so many downsides to owning the NX over a top of the line CR-V.
Good luck and tell us what you buy!
