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.

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:

Junkyard Gem: 1997 Pontiac Sunfire SE Convertible

For the entire 24-year production run of the GM J platform (best known for the Chevrolet Cavalier), the Pontiac Division offered new J-Body cars for sale in the United States. First there was the J2000, followed in quick succession by the 2000, 2000 Sunbird and Sunbird. The Sunbird stuck around until the Cavalier got a major redesign for the 1995 model year, at which point Pontiac changed the car's name to Sunfire. Today's Junkyard Gem is one of those early Sunfires, a top-of-the-line SE convertible with the optional big engine and manual transmission. The Sunfire was an extremely close sibling to the same-year Cavalier (by the late 1980s, all the other US-market GM divisions had dropped their J-cars, which meant no more Skyhawks, Cimarrons or Firenzas), quite difficult to distinguish from its near-twin at a glance. The base engine for the 1997 Sunfire convertible was the pushrod 2.2-liter straight-four that powered so many J-bodies of the 1990s. That engine produced just 120 gnashing, valve-floating horsepower, not much by late-1990s standards. For a mere 450 additional dollars, however, the 2.4-liter Twin Cam engine and its high-revving 150 horses could be had by '97 Sunfire buyers. That's what's in this car. This is one of the members of the Oldsmobile Quad 4 family, though some fanatics will yell at you if you apply that name to the versions that don't have big QUAD 4 lettering cast into the valve cover. This is the most powerful engine ever used in production Sunfires. For 1997, Pontiac offered a four-speed automatic transmission for no extra cost in the Sunfire convertible. Buyers of all other Sunfire models that year had to shell out either $550 or $810 ($1,026 or $1,511 in 2023 dollars) for a two-pedal rig. That means that the buyer of this car really wanted the five-speed manual transmission (or just hungered for the $810 credit offered in the fine print for takers of the manual). Plenty of free-breathing engine power, five-on-the-floor driving enjoyment and the open skies above. What a fun car! This one made it to nearly 180,000 miles. For this car with the Quad 4 under the hood and a clutch pedal on the floor, the MSRP was $18,539 (about $34,584 today). Its Cavalier LS convertible twin with the same engine/transmission setup cost $17,365 ($32,394 now). This car has a bunch of options, including the 15" Rally aluminum wheels, so the out-the-door price would have been higher. The last year for the Sunfire was 2005, same as the Cavalier.
