My 2011 GT has the electronics pkg and after having it, I would not buy a vehicle without it..... yeah, it's that good - IMHO.
We have received a bunch of 2011 GTs at the dealership (Noth Atlanta Metro Area, GA) but they are all automatics and mostly convertibles. I got one of two 6 spd MT82 trans
equipped vehicles so far. Plus none of the others we have received have the Brembo brake pkg., either - again, something I would not overlook; the brembo pkg is awesome!
Ford is all about eliminating driver distractions and the driver can control climate, radio, navigation, etc all through voice commands with the electronics pkg. Too hot in the car? No problem. press the sync button say "climate, temperature decrease", and it will drop the temperature. You can control many, many features through the Sync system if equipped with the electronics pkg.
