1939 Pontiac Ghost Car commands $308,000 at auction

For the 1939 World's Fair, Pontiac built a Deluxe Six bodied in Plexiglass. Part of the Previews of Progress pavilion in which General Motors' Futurama showed off what was to come in the world of autos, the 'invisible' Pontiac is credited as the first transparent car in America. And there were no shortcuts taken with its body: the Plexiglass form was fabricated by the company that brought the material to market in 1933, Rohm & Haas.
The see-through sedan was sold at RM Auctions' St. John's auction in Michigan on July 30, fetching $308,000. Not bad appreciation for a domestic oddity that cost $25,000 to build when new. You can check out the high-res gallery of its innards, including copper and chrome metalwork and white moldings and wheels, and get the exhaustive details on it after the jump.

2008-2009 Pontiac G8 recalled over airbag concern

General Motors is recalling around 38,000 Pontiac G8 sedans from its 2008 and 2009 model years. The National Highway Traffic Safety Administration reports that the cars may have a passenger-side airbag flaw that might prevent proper deployment in certain scenarios.
According to NHTSA, the airbag might not adequately protect a fifth percentile woman - that is, a woman around four-foot, 11-inches weighing 108 pounds. The New York Times indicates that the anomaly was found during a crash test conducted by GM's Australian branch, Holden, which was testing the G8's twin (read: Commodore) for head injuries. According to that report, the test in question is specifically tailored to simulate injuries to females, so the results do not apply to men or children.
The issue has been blamed on a seat position sensor that governs airbag deployment rates. NHTSA indicates that when the front passenger seat is moved all the way forward, the faulty sensor may inappropriately trigger a 30-millisecond delay between airbag stages, potentially leading to greater injuries.

What's driving the spike in air-cooled Porsche 911 prices

Classic car prices have been racing skyward in general, but prices for air-cooled (pre-1999) Porsche 911s are ascending like they're strapped to rocket boosters. It's been going on for years, and every year people are surprised by how outrageous it's getting: Classic Driver covered it this month, as did The Truth About Cars who included this example of a "scruffy" 1993 RS America with 215,000 miles asking $80K; Mike Spinelli at Drive riffed on it at length last year along with a host of classic-car-market observers; Porsche forums were at it two years ago; and let's not even get into the 993 Turbo, going for prices so high you have to lie down to look at them. Speed Academy has run a piece looking at why it's happening, one theory being that regular-guy owners are hopping on the runaway-price wagon without any good reason. As in the example of that high-mileage, scruffy 911 RS America at Bring a Trailer, the owner sees pristine examples valued by Hagerty at $170,000, and even though the average value is $93,238 he thinks something like, "Mine's got to be worth half of top dollar ..." The tide - even one rising on air - makes it hard to find decent prices. Then there is the flood of money into the market. In spite of articles that try to temper investors' outlooks on collectible cars, other articles in places like the Financial Times and the Guardian promote vintage metal as a safe place to put money and reap astonishing returns. Speed Academy thinks one side effect of high 911 prices is that responsible enthusiasts are turning their attention to cars like the BMW 2002, E30 M3, and E9 3.0CS, saying their prices are "sharply on the rise." The entire article is worth a read since it goes into markets far afield from pricey German steel, but incredibly, the entire piece was actually inspired by a 1997 Acura Integra R that sold for $43,000 on eBay. So while this could be the best time to get into the classic car market if you know what you're doing, it is certainly the best time to do your homework. Related Video:
