1. Heated seats would have been nice but no dice. My ski gear works well.
2. Leather storage pockets. hmm. Big enough for a phone but not much else. Don't keep maps since I use a Garmin GPS when I have to. As for keeping things in the cab, I don't. Everything necessary goes in the boot where it is nominally dry and out of sight. Only things I find I carry in the cab on a regular basis are water bottles and a large umbrella.
3. Intercom. Waste of money for me. Wouldn't use it. Don't engage in thoughtful, intimate conversations with this thing...
4. Toad Immobilizer. Have it. Use it. My insurance critters don't seem to care about it. For added security the steering wheel comes with me!
For later additions, I would strongly encourage anyone to put on the fixed center mirror between the wind shields. The side mirrors are both convex and vibrate so much as to be almost worthless.
