I decided to keep my order for the 2WD and bought my car over the weekend. I still have doubts on whether I made the right decision by not getting the 4WD, but I think I did. Resale value is not a factor where I live. Most of the dealerships in southern California carry 2wd Tahoes. The people here actually prefer 2WD over 4WD. Also, you can't compare 4WD to AWD. You can't use 4WD in regular traffic to maneuver in and out of traffic. The only place I'd be using a 4WD is in the mountains during winter if I go snowboarding, but I can just pop on some cables and get better traction than I would with the 4WD.
