I got my car fine tuned (heck, it ran pretty darn well already) last week. They changed the springs in the distributor and changed the jets. The car now makes more power and gets considerably better mileage. I drove the car 280 miles last weekend and I figured I saved around 30 bucks in gas. To me, that is like free beer money

25.7 mpg hwy cruising at 70mph with no passenger with 3:08 rear and 5th overdrive. Runs around 2k rpm's doing that. Lately I have been "hypermilaging" the car, meaning running it in town in 4th or 5th at 35 to 45 mph and 55 mph on the freeway taking off really slow, keeping it under 2k for shifts and coasting in neutral. Not particullarly fun to drive in this manner, but it's paying off in the extreme. Can run the car all week commuting and driving all weekend and only use 8 gallons of gas. EFI and small blocks rule -John

Me too!

I want my Cobra to represent the power and prestige from the past. Not an economy car for today.
I don't drink or smoke so I get my pleasure from driving my car.

Default What mileage??

My car burps when I switch it off!

My wallet cringes when I rock up at a servo....@ nearly $1.65 per litre

WHO CARES!! Just enjoy them.

Buy the Hybrid Kirkham if you're looking for economy.

My 2 cents

Stef

Hey, don't get me wrong. I drive the hell out of my cobra on the weekend, but I also "daily drive" the car to work across town. Why should I waste money driving it like I stole it everyday? -John

To each his own. I wouldn't want to drive my car everyday. It is more of a weekend getaway for me.
I don't drive my car like I stole it every time I take it out.
Just for me a Cobra represents an era of brute horsepower from a simple carburetored engine with all its faults and it beautiful rawness.

My daily driver is a work van loaded to the max. I am lucky if it get 10mpg.

Cheers
