My much older brother had a ‘77 Thunderbird he bought new with the coldest AC that I’ve experienced. Seems like you could see your breath in that thing.
Our 2010 Camry that I sold last year was pretty darn cold too.

With those ridiculous electric radiator/ac fans - errrr I mean mini jet engines. If you haven't heard a modern Mercedes on a hot day just imagine standing in front of a small jet engine.The MB's I have had will freeze you after a while no matter how hot it is. The hotter it is, the colder it blows it seems.
Anything Ford.
Give the old Ranger in my signature five or six minutes, and the cab will be as cold as a meat locker.
Both of our Hondas, not so much. Adequate, but not exceptional.
Our piece of junk 02 Focus AC works pretty good, the wife will tell you the only reason we still have it. Granted had to redo it twice, first shop didn't put oil in the compressor. Watch for those "mid-year" changes Ford is famous for if you have to buy parts.Wouldn't know nor would I really care how cold it was other than cool. Nonetheless, the last time I used the AC in my daily 2004 Focus was in 2008. I'm sure all the refrigerant has leaked out by now and it needs a recharge if I ever get around to it. Have the equipment and 3 cases of R-134a.
I vote my 2005 Silverado. Coldest I've felt and it comes on within like 20 seconds of starting the engine.Now that we are in the heart of summer, what vehicles that you have driven (or ridden in as a passenger) had the coldest air conditioning system? I'm particularly interested in hearing the impressions of the vehicles that were used in the extreme heat locales like Arizona, Florida, Texas, Middle East, etc. Hoping that we can collectively identify the BITOG top 10 "meat lockers" on wheels.
Let's limit each list to your top 3 vehicles as the list can be extensive. I'll kick it off with my top 3 (YMMV):
(1) 2003 FORD Expedition Eddie Bauer Edition (w/ dual A/C)
(2) 2000 NISSAN Xterra XE
(3) 1998 FORD F-150 XLT
