Acura is not really even luxury. Those shiny calipers have long been tarnished.
The 2016 Buick Envision Premium l is about $10,000 less than the NX but doesn't offer $10,000 more...but actually offer less. The warranties are about the same except for one or two years difference on some coverage they basically the same. But you can only transfer the warranty once with the Lexus for a $25.00 fee, Buick is unlimited warranty tranfers. The free maintence schedule has coverage of all luxury makes with 1-year 10,000 miles whiles are close to double the coverage. Synthetic oil every 5,000 miles is not cheap with the Lexus.
The 2016 models I compared the NX did not offer leather where the Envision did, NX does not offer tri-zone climate control where the Envision did...all those features add up to make the NX a even worse than it's price. The gas mileage worse in the NX along with longest braking distances from 60 mph in the segment.
NX200t/300h deep dive - Car & Driver
According to CR video including the Envision and Jaguar Fpace the Buick is as you already quoteD and the Jaguar a super CUV. But comparing braking and collision avoidance maneuvers they are within a couple feet of one another...hmmmm. Of course no one pays full MSRP in these segments but the Envision is still the cash cow at $33K discounted. The NX has longer stopping distances and is 5 mph slower through the avoidance test
Then CR had this to say about the NX200t:
But it's not convincing, and much of that has to do with its RAV4 underpinnings. Nothing against Toyota's super-popular small SUV, but luxury is not in its DNA. The NX's looks promise derring-do performance, and its handling is indeed sharp. It's responsive compared with a typical Lexus, but handling and braking are a notch below competitors from BMW and Audi. And the NX doesn't deliver the quiet, calm, and serene ride you expect from a Lexus. Instead, it's as firm and controlled as an IRS audit. The performance doesn't match the looks -- like when a peach-fuzz sibling borrows his big brother's leather jacket, the appearance isn't quite right. Inside the cabin, the NX once again falls short of Lexus standards. You're not cosseted with parlor-room luxury. Many parts and panels look and feel cheap, costing the NX points for fit and finish."
One funny note is that they both have a cd player slot! Buick holds it's value well playing the near-luxury area where Lexus models do not fare well in residuals but are on par with their luxury segments and sometimes worse in the case of the GS.
