Jay Leno puts carbon fiber wheels to the test on a Porsche 911 GT3 RS

Jay Leno's Garage usually focuses on looking at cars new and old, speaking to their owners and then Jay taking a drive to see what he thinks. However, Leno throws his usual shtick to the curb this week to do a full product test of the carbon fiber wheels from a company called Carbon Revolution. If you're not interested in hearing about wheels for 18 minutes, don't worry. They get mounted on a Porsche and are tested back-to-back with stock wheels, and Leno takes the 911 for a track test, too.
While carbon-fiber wheels aren't exactly a new idea, Carbon Revolution's goal is to create a lightweight, one-piece product that can be mass produced. The company even claims that it already has a deal with an OEM automaker to offer them on a vehicle in a few years. The key to the technology is that it doesn't need an expensive autoclave to be made.
In the meantime, the company's carbon fiber wheels are available as an aftermarket option for about $15,000 a set, according to the video. They weigh in at about 15.5 pounds each and offer OEM-levels of stiffness, so they could cut some unsprung mass off of a performance car. Watch here as Jay and his mechanic Bernard lap Willow Springs and give their feedback about what they think of this cutting-edge technology.

Jaguar F-Type squares off against Porsche 911, Aston V8 Vantage with Chris Harris

Chris Harris is back on the job, taking on really really difficult car questions like: Which enormously sexy and good-to-drive, high-performance convertible is the top of the heap? As one of the hottest cars in the luxury space right now, the Jaguar F-Type S is, of course, in on the action. Competition comes in the form of the Aston Martin V8 Vantage Roadster and the Porsche 911 Carrera S Cabriolet. Sun-loving CEOs who despise test-driving need look no further.
Scroll on below for a fully featured (with a running time of more than 20 minutes) comparison video. Harris does his best to entertain - in a typically nitpicky and made-up-British-words fashion - and the moving pictures are lovely to look at. Kick back, pour a pint and get your weekend started off right.

eBay Find of the Day: 1981 Porsche 928 convertible by Carelli

The Porsche 928 was perhaps the consummate European GT of its day. With a powerful front-mounted V8 engine that grew in displacement as the model years went on, it was capable of eating up the miles at triple-digit speeds in great comfort for occupants. It was also an unusual beauty, with its sharp front and curved rear featuring innovative integrated bumpers.
Currently for auction on eBay Motors is one of the rarest 928s you're likely to find, in a handsome combination of Guards Red paint and tan leather interior, though we wouldn't mind a less-showy finish to the factory wheels. According to the seller, this car is one of eight 928 convertibles by Carelli Design, a firm that's still in business.
The auction claims that these cars were made in 1981 as a feasibility study between Carelli and Porsche for a possible production 928 convertible. The seller says he worked at the dealership where the car is said to have been originally sold $103,000. To remove the roof and hide the convertible top, there were significant changes made to the body and interior, including redesigned doors and a completely new trunk. As you can see in the gallery, when down, the top is completely hidden in a very factory-like fashion. When up, it looks slightly awkward, though (and we'd really like to see a rear three-quarter view to check out the blind spots).
