I'm looking at Carmax right now (which is where I got my 2019 Yukon SLT 4x4 in December of 2019 for $42,998 with 34,000 miles) and this is what you can get currently;
1) 2018 Suburban LS 4x4 with 33,000 miles for $43,998.
2) 2020 Tahoe LT 4x4 with 34,000 miles for $51,998.
3) 2017 Yukon Denali 4x4 with 71,000 miles for $47,998.
4) 2017 Yukon SLE 4x4 with 36,000 miles for $39,998
There's more available than this but it's less than it was a year and a half ago, they had much more inventory, however this gives you an idea as to Carmax's pricing. I still feel their pricing is better than any dealer. Agree/disagree?
PS, this is also in the Chicagoland area/northwest Indiana. Most of the vehicles are somewhat local but I'm seeing an Ohio and Kentucky vehicle as well, it seems that their nationwide availability is low. I remember seeing all sorts from New York, California, etc. Nada right now in regards to the Chevrolet/GM full size SUV platform.
EDIT - Nevermind. I did not have "nationwide" selected. They have much more than I originally reported above. I originally was only shown vehicles within 250 miles.
