I would never buy a new car - all those lost dollars the second it is driven off the show room floor? Not for me.

Hybrids/alternative fuel cars not really good value or environmentally friendly - YET. However, they will improve.

When that happens I will trade in my ancient, reliable, very fuel efficient Mazda for a late model something.

If you want to know how fuel efficient your car is check out this site - it's American but from memory you can convert to litres. And it is the luxury end of the market that is the least fuel efficient, a fact that I indulge myself with a little schadenfreude. Heh Heh.
