@RichieT I don't know if you've ordered yet, but I would say the remote comfort pre-conditioning is a must. My Technik came only with the standard pre-conditioning, which means you can set climate control from the MyAudi app to heat your car before you jump in in the winter, or cool it in the summer (preferably while plugged in to a charger).
The standard function just uses the previously used climate control setting . e.g. if the last time you drove was a sunny afternoon, you might have had a cool setting. This cool setting is what the MyAudi app will use if you turn on climate control from the app.
The remote pre-conditioning option allows you to set the climate control temp from the app. Its a £100 add-on from factory. I'm booked in next week at the dealer for something else, but I'll see if this can be retrospectively added.
Also be aware the car does not come with roof rails and there are currently no options to fit roof bars to this car without them. Might be an option you'd want to add. Or have the factory towbar option added £650.
There is another alloy wheel option on the Technik, can't recall the name, but they are a little more aero and give a few more miles of range (literally 2 or 3 miles).
