Very true, and similar to the principle I had when I ran a small fleet, you can have anything you want as long as it isn't gonna cost more than a (insert car I chose here).
If someone wants to stick an Alfa on their drive then as long as the contract has a guaranteed replacement car there's no problem. And if it means that they go out of their door in a morning and it makes them smile before going to work it's a good thing.
Of course you /could/ be a complete sod, and when someone's response to "what car do you want" is "don't care as long as it's auto" and get a Daewoo Lanos auto for them.
