I've owned a couple retired police Caprices and currently own a 2011 Caprice PPV (9C3). I think Tahoes get the same upgrades in heat management and suspension along with the gutting of amenities. Getting older, I kinda like the amenities and it's why I'm on the fence. Police units are usually well cared for. "Low" mileage units can be deceptive: The idle hours tells a story too. I learned a Tahoe PPV I was looking at has less than 100k but 9600 hours of idle time. Quick math works that out to an average of 6-7 hours of daily idling. Sounds like a patrol car: no thanks. One thing I've learned is that it doesn't hurt to wait for the right thing to come along, and that's what I'll do.
