Today , 41 deg F in Naperville , 39 in Elk Grove. Headwind all the way ( NNE 15MPH ) 35.1 miles , fcd = 58.0 x .943 = 54.7 MPG. Tank is at 304.4 miles , fcd = 67.2 x .943 = 63.4 MPG. I'm supposed to go drive a 2014 Civic 5MT today after work. I know that Carmax wants more than other dealers ,and perhaps the cars have a better inspection and warranty , but they want $16,000 for it. Yeah , the car only has 5K miles , but KBB says the high end of the range is $12,800. I have heard that CarMax doesn't negotiate on their prices. If that is true...…….. not sure if I wanna go.
