Although I doubt even a 4x4 truck or SUV would have been adequate for where they were.
"Wasn't it a Saab that the Kims got stuck in? Pity.'
From the overhead video that I saw, it looked like a Saabaru ... a rebadged Subaru WRX wagon, the Saab 9-2. Some things never change with GM.
The Kims were driving a Subaru Outback wagon AWD.
I can think of one 4X4 built in the past 30 years that may well have gotten them out on it's own power. A stock 1978 Chevy K-5 Blazer full time 4X4 automatic that did not have lockouts installed. They were purposely built high off the ground from the factory and IMO is the best all around stock 4X4 ever built by an American manufacture. 350 V-8 with plenty of power too.
I've owned two and nobody is getting the one I have now even though it is a straight shift 3 speed with a granny low. I've taken mine through 2 feet of snow up the side of a ridge and it didn't even put up a fuss. The newer SUV's though you're likely right. The original Blazers were one of a kind. The new ones come no where close.
