We were stoked to find that our buddies over at Jalopnik have discovered a G-rated version of the parking-retaliation merchandise we’ve talked about here before. What the cheery illustrated stickers available at IParkLikeAnIdiot lack in, um, colorful language, they make up for with the fact that they involve defacing the offender’s vehicle. You see, the stickers can’t be ordered in batches of fewer than 20, suggesting that typical customers aren’t exactly purchasing the novelties for display on their own vehicles, if you catch my drift. This aligns the business with guerrilla vehicle-stickering campaigns of the past, such as the one a few years back that encouraged people to plaster the most oversized SUV’s with stickers that read, "I’m changing the climate, ask me how!"  While a lot of you have agreed that incompetent parking makes you see red, particularly when someone else’s crappy parking job endangers your vehicle, I’m wondering if you think it’s ever justifiable to smack a sticker on someone’s ride. Maybe if it keeps you from keying them?

The concept behind AMG’s the Launch isn’t complex, but it’s still pretty fun. The point? Just get the best start you can. That’s it. I haven’t been good at video game in like 20 years, so predictably, I kind of sucked at it. But the visuals are cool, and the sound of the motor is sick. My best time is 4.772. What’s yours?

Our latest new car challenge was neck and neck for a while, but then the IS-F pulled ahead for a decisive victory over the M3 Sedan. That’s the second rough week for German auto manufacturers in the blog–last week the Quattroporte gave the Panamera a brutal smackdown.

So what match up do you guys want to see next week? Let me know if you have any ideas. Maybe it’s time for some trucks…

Personally, I think you’re just asking for trouble if you advertise illegal activity on your vehicle. Remember this Onion article? There’s totally a grain of truth to it. So there’s no way I’d be caught driving this pot-themed Porsche—or any Porsche, really—around Seattle. But the rules must be different in Russia. Just check out the mellow mood of this Cayenne! I particularly like the badging on the tailgate, and the windows look to be dark enough for, um, privacy, but I have to admit that the Rainbow Brite-styled interior really harshes my buzz.

As International Auto Show season heats up, it’s not hard to shed a tear for all those far-out concept vehicles that never got to see production. Take the Saab Aero X, inspired by the manufacturer’s aircraft division, with its lift-off cockpit and panoramic wrap-around front and side glass. It was unveiled in 2006 at the Salon International de l’Auto and was always intended only as a "design study." Maybe it’s just as well that it never made it to production—Sean says he recalls an embarrassing incident from the time in which the working Aero X prototype died at a gas station during testing and had to be jump-started. Still, even if the Aero X turned out to be unreliable junk, I’d rather see it on the road than not.  I mean, just look at this insane promo video of the cockpit mechanism in action. How about you? What concept cars past do you regret never having been built?

I’m sure a lot of you are familiar with the US site Carsinbarns.com. Well, some guys in the UK started this thread on rotting exotics, with tons of pics from all over in Europe (and elsewhere). The most shocking to me were the Daytona below and the Muira on the first page. Warning: one avatar in the forum thread is not safe for work.

The guys over at The 1970 Hamtramck Registry scanned in the 1967 Chrysler Interior Selection Catalog. Some of the drawings are hilarious. They definitely don’t do luxury like they used to!

If you’re looking for classic French-car charm without the accompanying reliability headaches and parts obsolescence, Japanese boutique tuner DAMD has just the conversion for you: an updated Renault 4L replica built on the Suzuki Lapin. The styling cues borrowed from the classic 4L, which was produced from 1961-1994, are spot-on, right down to the chrome center caps and the square grille/round headlight combo. The interior is sufficiently modernized, but with retro touches like the Alice-in-Wonderland upholstry. CarScoop says this sweet conversion was being shown off at the Tokyo Auto Salon.

Demo cars, demo cars, demo cars… They were all over the place at CES, and we just couldn’t get enough of them.

• Check out this crazy post-apocalyptic-themed Kicker van, which sports two of their monster Warhorse amplifiers. This mean machine means business!
• SSL Audio had a rare Morgan in their booth. You don’t see too many of these in the US, so it was a treat to see one up close.
• Memphis has jumped on the "thin is in" bandwagon and had their new uber-thin composite subwoofers and skinny new amplifiers on hand. Pretty damn sexy stuff.
• Juan and I checked out Kenwood’s new gear and decided the new KDC-X592 is one super-sexy CD player; its classic styling has a sweet modern twist.

Ok, to follow up on yesterday’s post, here are the three pony cars side by side. Obviously, we haven’t seen the final final version of the Camaro yet (though the silver one below appears to be very close to the white pre-production models spotted recently). But which is the best design?
