need a new car - ideas please

[NaughtyNigella]

I need a new car. i have to have one to get to work, do shopping, ferry children etc.)
it needs to be small, cheap, reliable, and look good (i'm so shallow - also need air con and CD player).
i want to get the 'greenest' option. any ideas?

Go for smallest engine size that is still as big inside (seats, space) as you need.
Type 'Green cars' into Google to find websites that list different sorts of Green car options (CO2 options, etc.).

How you drive is as important as what you drive. Not using AirCon, for a starter, would reduce the env. impact a lot.
