hora....who cares about mpg......
600 miles/week commuting coming out of my wallet.
At 22mpg (RX-8) that would cost me £126.30/week
At 58mpg (Ibiza 1.9TDI) it costs me £47.90/week
assuming both fuels are £1.02 which they are where I fill up currently.
But, of course if you are buying a car like the RX-8 you aren't so bothered by fuel consumption & you perhaps wouldn't buy it if you relied on it as a mile muncher. Although my mates Corolla T-Sport (198bhp) with variable cam thingies that doesn't really get going until 5 or 6k rpm - he still manages to get 40mpg out of it on his commute and it's no slouch.
