The Title says it all - See Here

THE WORLD HAS GONE MAD!!!!!!!!!!! I am seriously shocked that the mustang would even be remotely comparable. Now we need the Stig to take the Mustang out and see how good it really is!

One more thing: no one willl call you a cock when you drive a mustang.

Aww, from the title I was expecting a bodybuilder fighting a Panzer

Ford is really on a roll these last several years, and this is just one more example.
When it comes to cross-shopping these cars, about the only people who would consider both models for a new-car purchase will be those who do plan to use them at the track or autocross. But for the average person looking for a street performance car, I don't think you'll find many M3 shoppers walking into a Ford dealership looking to save $25k, and likewise I don't suspect many Mustang 5.0 shoppers (hey, it's a real 5.0 for once!) will look at the M3 as an alternative purchase.
That $25k difference will get you things that won't won't make a difference at the track but do present a nicer daily-driving experience. Not sure that it's $25,000 nicer, but then again I'm not in the market for either one.
Anyway, kudos to Ford. Well, and to BMW - for making the M3 a tough benchmark over the years.

Yeah, or a Tiger tank with a silly tagline like "Got the Tiger by the tail".

Aww... they aren't going to put them up against a Z06 or ZR1?

Also, can someone tell me how much gas the two use in comparison? I know American cars tend to suck gas as if their life depends on it so I'm curious.

The Ford is rated at 17 MPG city and 26 highway. The M3 is 14 and 20. For their size (too large for my tastes), cars in the US market have gotten quite a bit more fuel efficient in the last decade or so. Of course, all that goes out the window with an eager right foot...

I thought it was a gay porn movie. I leave disappointed-- wait, what?

That's because no one who has one will drive one.
Seriously, I only see chicks driving those POS cars.

That's only because the Chicks who hung with the guys who had those cars can now afford their own. Equal Rights !!

That reminds me that I know a 65 years old lady who owns a Dodge challenger, and I don't like when she parks her car next to my Vibe.

If that were true then I should be seeing a roughly equal amount of guys in the same income and age ranges driving them, but I don't. And seriously, in the 80s owning a Mustang was about as prestigious as owning a Camaro, i.e. white trash. Since the Mustang has been "re-invented" it's primarily a chick car. Oh, I'm sure the chick owners disagree, I've had gals who owned their cute Doge Durangos swear up and down that dudes loved their car; it was still a chick truck. What they didn't understand that really meant is the same thing it meant when guys envied my ugly yellow pickup with dual cab, extended bed, and dualies as a teenager. They didn't envy my ugly truck, they just liked the really big 454 engine.
