The Dodge Challenger SRT Hellcat is undoubtedly one of the baddest cars on the road today. With a 707-horsepower supercharged V8 snarling under the hood, the coupe can go down the road like a bat out of hell. There's not much that could make one of these muscle machines much more menacing, but a seller on Craigslist has one bizarre solution: offering a hellacious Hellcat with a VIN marking the Dodge as the beastly 666. What's the price for such unholy identification? That's a cool $89,000 – around $30,000 more than a brand new, less sacrilegious example.

The seller claims that the Challenger's blasphemous number makes the vehicle "one of a kind," which is true only to the extent that VINs ending 665 and 667 would be similarly unique. The seller also says in the Craigslist ad, "This car is sure to become a collector's item and will only increase in value." There's no question that the Hellcat is a special machine, and the models just might be worth something decades into the future. Expecting that a future owner is going to care about the VIN seems pretty optimistic, though, unless this is either the first or last example, which it's not.

To the credit of this superstitious seller, the Challenger appears completely untouched with all of the warning stickers, paperwork and even the plastic still covering the seats. So, the new owner is at least getting a practically untouched example.

At 75.7 inches, the Dodge Challenger isn't actually much wider than, say, a Ford Mustang – but it sure looks it. Performance aside, it's one of the most imposing vehicles on the road with more presence than just about anything else on wheels. Liberty Walk isn't about to leave it at that, though, and has designed its latest body kit for the Mopar muscle car.

The widebody conversion for the Challenger includes wheel-arch extensions, of course, but also a front splitter and ducktail spoiler. The components are made of fiberglass, and can be ordered separately or as part of a complete package, priced in the UK at £4,460.00 (or almost $6k at current exchange rates).

It's not the first time we've seen a Challenger with a Liberty Walk kit, mind you. But it never fails to impress, giving the Dodge an even more planted stance on the road – especially all in black and when paired with Liberty Walk's Airexx digital air suspension – whether it's packing a humble V6, the top-of-the-line supercharged Hellcat V8 or one of the Hemis in between.

Then again, if price is a concern, the cash spent on the body kit could arguably be better put towards upgrading to the next engine up. Because a muscle car like the Challenger has always been about delivering the most bang for your buck.

The 2017 Dodge Challenger earned a maximum of 5 stars during collision tests with a pole and another vehicle at speeds of 32 mph (51 km/h) and 62 mph (100 km/h).

"This proves the 2017 Dodge Challenger is much more than a great-looking car," said Mike Dahl, head of Vehicle Safety & Regulatory Compliance, FCA North America. "It reflects our commitment to delivering exceptional occupant safety in every vehicle segment."

During the side-impact testing, the Challenger's high-strength steel body structure, combined with the careful integration of side-guard door beams, proved critical, though supplementary restraint systems also contributed to the performance. Furthermore, all trim levels for the Challenger offer driver and front-passenger side air bags as standard, as are front and rear side-curtain air bags.

As for a look into the 2017 Challenger's active safety systems, the NHTSA noted the availability of Forward Collision Warning (FCW), Blind-spot Monitoring (BSM) and Rear Cross Path detection (RCP).

Since this latest generation Challenger was introduced back in 2008, it has achieved five-star scores every time it was tested by the NHTSA - though it trails newer rivals such as the Mustang and the Camaro in IIHS crash test ratings.
