Oh boy...good luck with the comments on this one!
I chose the Palisade because for one, it was available. I wanted the Telluride SX Prestige Nightfall. Couldn't find one and to order it was going to take 3-4 months with markups from $2000-$10000. I never even considered the Palisade until then so we looked at one and fell in love with it. The interior is so much better and with exterior mods, you can make it look pretty tough in my mind. I have White and powder coated the wheels, chrome delete and tinted the rear lights. So I made my own Nightfall. I only had to wait about 2-3 weeks for my Calligraphy to arrive and I paid MSRP. Some markets have them discounted now but others also have markups so it all depends where you live and access to multiple dealers.
Regarding the GV80, awesome SUV, BUT if you want or need a functional 3rd row then it's only available on one trim (not even the highest trim) and it's not roomy at all. Plus maybe $15K to $20K more? And it's hard to get one as far as I know. When I was looking in Oct I was #50 on the list. I bought the Pali same time and I still haven't received a call on the GV80. That was just to test drive it and the Genesis manager said he would call down the list when he had one.
In the end, test drive them all but the GV80 is completely different class. I also considered and drove the Lexus GX460. Great brand and SUV but it hasn't been updated in 10 years and the Palisade blows it out of the water with tech. Maybe reliability will be a concern with Hyundai, who knows.
