I sure don't want to live where Carkle does.
So, picked my Passion hard top up on 2/2. Using a method close to Suze's, I top off with three clicks of the pump and divide my mileage per tank by the amount purchased (been doing this for years checking mileage against on-board computer's info with near perfect results). This last tank I took the car up to LA from SD with a passenger AND doing about 80-85 the entire way up and back. Drove around a little bit there in the La Brea area (went to the LACMA display of the BMW Art Cars) and was only at 1/4 tank when we got back to SD. The g/f took the car shopping yesterday (first time for her driving it, totally unsupervised so I'm talking her description of Cautious driving style at face value), and I drove it to and from work today. Averaged out to 39mpg. I had guesstimated the LA trips mileage at about 41mpg, so this sounds about right for the overall tank. I'm heading back to LA this weekend to the Glendale area, so I'll get a bit of a better average I think. We'll see.
Other tanks that have been basically pure city/street driving have been about 32mpg. Not spectacular, but better than the 19mpg and 17mpg my other cars get doing the same commute. I do have a lead foot, although I'm being good with the Smart so far due to the break-in period (which I will be out of this weekend

).
