After lusting for a Hybrid for several years, I finally found a like new one that I could afford, a 2009 Yukon. Highly recommend Jim King of King Motor Company, Marion Arkansas, just west of Memphis. He carries only super nice, higher mileage vehicles, often Hybrids, and has a Silverado hybrid currently in stock. He was honest in description by phone, and checked several items I asked about, fixing them before I arrived from out of state. He made every effort to ensure I was happy before delivery of the Yukon.
Love my Hybrid's mileage so far, averaging 19.8 in town. It auto stops at every light, I can slowly get to 28 mph on battery, and V4 mod at 70 shows 24-25 mpg. I could not be happier with my old Tahoe averaging 12 in town.
Thanks to everyone on here for all the great information contributed.

 

Congrats on many miles more or driving it. Make sure to use only mobil 1 extended performance oil. It is the recommended oil. No Dino or blend please.
