There are some simply clever ideas indeed, like
- 5 little knobbies at the bottom of the drink holder, so you can open a bottle of water with one hand without looking
- a little umbrella in the door/under seat, because we never have one handy if needed
- ice scraper in the fuel cap, accessible from outside and can be stored when wet
- little plastic flap at the inside of the windshield, which can hold the parking tickets
- standard wall plug between seat
- ...
The usermanual even has a section with these simpy clever things ;-)
You could reduce the time needed to a half of it. So costs are halved with the same work force - plus you can do double the movies
