Preserving automotive history costs big bucks

$1.8 million is spent each year to maintain GM's fleet of 600 production and concept cars.
When at least two of the Detroit Three were on the verge of death a few years back, one of the tough questions that was asked of Ford, General Motors and Chrysler execs - outside of why execs were still taking private planes to meetings - was why each company maintained huge archives of old production and concept vehicles. GM, for example, had an 1,100-vehicle collection when talk of a federal bailout began.

BMW Z8, Lambo LM002 sell for $192,500 apiece in Detroit [w/poll]

Think a car are a bad investment? That all depends on what kind of car you're talking about. Because while most cars depreciate in value as soon as you drive them off the lot, others can do even better than hold their value. The cars that appreciate tend to be pretty high-end exotics, but they don't have to be multi-million-dollar classics to command a premium at auction. Just look at the results from RM Sotheby's Motor City sale in Detroit this past weekend. The auction house moved a solid $7.4 million worth of metal, which is pretty impressive when you consider that – unlike events at Lake Como or Pebble Beach – not one of the lots dipped into seven figures. 1930s-era American classics performed the strongest, with Duesenbergs, Packards, Auburns and the like all fetching hundreds of thousands. But what intrigued us most were the European exotics that rounded the top ten results. Amidst the Depression-era American steel were a BMW Z8 from 2001 and a 1988 Lamborghini LM002, each of which sold for an equal $192,500. Hardly the highest figures paid for European exotics this year, but considering how much they were worth just a few years ago, they've proven solid investments. BMW only made 5,703 examples of the Henrik Fisker-designed retro Z8, of which only 2,543 were brought to the United States, where they originally sold for $128,000. The most anyone had ever paid for one at auction, according to Sports Car Market, was $184,082, just this past March at Silverstone. That makes the price achieved this weekend a new record for one of the slinkiest vehicles the Bavarian automaker has ever made, representing an impressive 50-percent increase in value over the course of fourteen years. This particular example – chassis WBAEJ13481AH60437 for those keeping track – is decked out in silver over black, with less than 15,500 miles on the odometer. This Rambo Lambo was produced early in the 301-unit production run, with the sought-after carbureted engine and 32,000 miles on the clock. It didn't set any records at the same price, other examples of the LM002 having traded over the past few years for over $200k. But considering that Sant'Agata originally charged around $120-130k for the SUV when it was new, its selling price still represents about 50-percent appreciation (leaving inflation aside).

Vorsteiner BMW M4 GTRS4 shows how to do a widebody at SEMA

Part of the joy of the SEMA Show is that all of the best tuners in the world are competing to show off their wares, and the challenge often pushes the companies into some absolutely insane directions. Case in point: Vorsteiner and its ludicrous GTRS4 wide body kit with the BMW M4.
According to Auto Evolution, the kit reportedly adds 4 inches in the front to fit 10.5-inch-wide wheels and a massive 7-inches more in the rear to snug in 13.5-inch-wide wheels, but spinning around the BMW in these images makes the changes look even more extreme. Beyond just the extra room in the fenders, the lower air intakes are ready to suck in huge volumes of cool air, and there's a front splitter to keep things planted. The front and rear extensions are joined by side sills that grow the farther back they go. Finally, at the rear, the M4 gets a reworked diffuser with mesh inserts.
This is just the type of automotive craziness that makes SEMA interesting. Take a lot at it for yourself in the gallery.
