I don't know why anyone would waste their money on a clunky junky Civic Si. The V6 Mustang gets way better fuel mileage, and the GT blows the doors off the Si.

Clunky junky?

Anyways, I considered a '11 Mustang V6, but I live in an area that gets dumped on by snow and studded tires are illegal. Since I have to commute 70kms one way to work, it's just not practical.

It just snowed today actually. The Si handled pretty good with all-seasons. I'm replacing them with winters this week though.

Plus comparing an Si to a Stang (esp the GT! what are you smoking??) is like comparing a Fiesta SES to a RX-8. They're not even in the same category! I'm sure we would all love to own new GT's.

Honda's proven reliable year after year. That's why I bought it.

You might want to look at a WRX for the winter aspect. 265 HP and AWD. These cars are amazing in the snow, especially with the manual tranny. They are also really fun and really fast for the other three seasons. I was getting around 27 MPG with mine.

Also considered. Hard finding one for less than 20K Canadian in my area. But definitely considering a WRX for my next purchase!

And by the way, I've never heard of a WRX owner getting 27 MPG. Most people on their forums (because I research them) average about 20-22 MPG.

"And btw I've never heard of a WRX owner getting 27mpg. most people on there forums cause I researchem them avg about 20-22MPG."

Yeah, well most people with WRX's are younger kids that abuse their cars daily. I drove mine very civil like, and consistently got in the upper 20's with it. It was a manual shift.

WRX guy, you might want to check your ECU and see what your air/fuel mix is running at, because you might be running too lean. I had the same problem with my old Stealth Twin Turbo.

Huh? What does this have to do with anything? Seriously, I don't understand your point here... could you clarify?

Check your ECU and see what your air/fuel mix ratio is. Your engine might be running too lean, as in getting more air and not enough fuel. That's why you're seeing higher MPG than average. Happens often on forced induction cars. Did you do any mods? For Honda it's a part called FlashPro.

Anyways, if you don't know anyone who can diagnose your ECU config, call around to shops or even the dealership to check to see what your engine is running.

My Dodge Stealth had similar problems. Had a friend plug his laptop into my ECU, and uploaded the proper mapping for what I had the car tuned for. It was like my car had the flu, and it got cured!

I'm averaging 35-38 MPG (70% highway) in my 2008 Civic Si. I have never gone less than 400 on a tank, and I have topped 500 on several occasions. The pre-2011 V6 Mustang would run the 1/4 mile in almost the same time as an Si, and I have never heard of anyone getting more than 33 MPG highway in one.

Wow, that is some insane gas mileage.

Note: I installed HFP exhaust, suspension and lip kit bought off eBay for less than 1/2 of what dealerships were charging.

Also installed a K&N intake, which gave me 2MPG more a tank! It's sort of loud though during WOT. Which may not appeal to everyone.

HFP suspension is awesome; it eliminates most of the bodyroll. It is a little bouncy at speeds of 50MPH though; that part I don't like.

I installed these all myself. And pre-'11 V6 Stang would have a hard time beating an Si in a drag or from a roll.
