Well Tim, now I know what "estate" means (station wagon) and the
"Sierra" and "Cierra" names belong to GM in the States.
We have 2 cars...a Buick LaSabre (considered an old man's car) it's
large with excellent mileage (35mi/gal). The other is a 16 yr old
Saturn (the beater).
With the Buick, and its electronic readouts I realize how much gas we
waste "getting up to speed". If everyone "actually" knew how much gas
they were wasting "with a heavy foot" we would save an immense amount
of "petrol"!
