Great SUV in an awesome color.
No problems. Beautiful color. Excellent sound system. Only thing I do not love is that it seems to have a hard time finding the key sometimes. It drives smoothly and has a great dashboard. The interior is fabulous leather. The notifications are a little sensitive but the radio has great features.

Good vehicle but can be improved.
Very comfortable vehicle. Steering wheel is loose, unlike my previous vehicle. Ride is smooth and hardly feel bumps. Acceleration and performance is great. Seems to use up a little too much gas. Space is adequate though there are some glaring deficiencies. Cannot adjust rear passenger seats back and forth. Also, driver is incapable of closing trunk without getting out of vehicle to press button on trunk.

It's very reliable, and comfy.
My vehicle goes quite fast although the breaks are late and that is dangerous! Luckily it's cheap to replace, it gets hot inside if it's a sunny day but the ac does cool it down a lot, I rely on it to go to work as it's not my fastest car but it still works great.

Luxurious full size SUV ever.
It is a most luxurious car I have ever driven. It is a bit expensive but it is worth it. I love it. Also, the company gave me 7 years full warranty excluding brake pads. The airmatic suspension in this car makes it more easier to drive. Also it has so much assisting features, everyone will be amazed. Awesome!

Extremely pleased but not in love.
It has classy lines, a well-appointed interior, and superb acceleration. The back seats are small and the drivers blind-spot is bad for someone short, although the mirror encroachment indicator compensates for that, somewhat. The radio has great sound and the dash display has a nice size.
