Only one issue for me. With the autos, when you move the shifter into the tiptronic gate, the entire centre cluster screen flashes up with the sports mode message for a number of seconds. In that time, you have no idea what gear you're in as the sports mode message consumes the entire screen. So if you're attempting to do a quick downshift (ie, to engine brake) you need to wait for the message to piss off before you know for certain what gear it's in, so you can flick the shifter the correct amount of times without being worried you'll accidentally grab first at ~60 kays and bounce off the limiter. Same goes with enthusiastic driving, let's say you want second gear suddenly, you throw it into the tiptronic gate but have no idea for the next few seconds whether the box is in 4th or 5th, do you shift down twice or 3 times? Get it wrong and you may end up with too high a gear or at redline in too low a gear. May seem small but it annoys me greatly.
The Falcon's sports mode message comes up in the centre of the screen without consuming the rest of the information around it, so as soon as you're in the tiptronic gate you know exactly what gear you're in, instead of waiting 3-4 seconds before knowing.
Otherwise car is perfect.
