If you are worried about fuel costs buy a small Japanese fuel miser. Cowboy is right it's smiles per miles you have with a V8. I should know as I have four I use on the road, they all vary on mpg and who cares, I don't.

no way,i only fill the falc up wen im goin on a decent trip away.certainly not every time it goes to the gas station.
on a decent trip you jus cant beat the comfort and power and effortless cruising that av8 car offers,they jus eat the miles.
well thats my opinion anyway.

Irun three cars. Mazda familiar is cheapest car to run Ive ever owned. Falcon is about average,and my project car is perhaps the hungriest car on theplanet. Strange that I dont care muchfor the mazda, think the Falcon is just ok but love the fuel scoffer.

id take the car. atleast the car doesnt break down for monthly repairs. would probably cost less in the long run too

My blown 454 T bucket got 13mpg on a trip. Had 3.0 gears out back and a pair of 750 edelbrocks on it. With 4.56 gears it was a total pig, as in under 5mpg.

And I drove a 289 Mustang recently with 2 barrel Holley and got a bit under 20mpg on a long trip

A wel tuned, carbed 4bbl V8 can be surprisingly economical, but most seem to be in the 15-22mpg region. EFI V8s I have owned have seen 26-27mpgs, and I drove a LS1 with a Harrops supercharger and cruising at 120+ kmh that thing was under 9 litres per 100 kms which I think is over 30mpg.
