The one option I'm really glad I spec'd is the auxiliary fuel-fired heater as it makes a big difference throughout the winter months. Switching it on via the app or using the in-built timers means you get into a warm and comfortable car and pre-heating the diesel engine makes it quieter. Also, even if you forget to pre-heat you can set it to automatically come on with the engine so that it heats up more quickly.

It's an expensive option particularly now that Engine Remote Start is available but with a diesel you have to run the engine for quite a long time at tick-over to generate any useful heat so your neighbours (and the environment) might not thank you.

The sound made by the aux heater is barely noticeable and doesn't attract attention. My concern with ERS is that if you used it in a car park, say, it might attract the attention of some miscreants who see an occupied car with the engine running and think they can just break in and drive off. This isn't possible but they may not know that so break in anyway.
