Ok, almost at 4K here with my Z-brid, the heat is definitely taking a toll on my mileage which makes sense, you have to power the AC with something either gas or electricity!! I am right at 41.2 I think for lifetime. Continue to like the car, although it is a bit of a gutless wonder for acceleration. The engine when it activates the ICE is loud, but levels out at higher speeds. I continue to love the technology and for the most part MyLincoln Touch. Whats up with you guys?? How is it going?
