Junkyard Gem: 1973 Buick LeSabre Custom Hardtop Sedan

The steps on Alfred Sloan's "Ladder of Success," in which you'd start your career by buying a Chevrolet and then move up through the GM marques as your wealth increased, stayed rigidly fixed from the 1930s into the late 1960s. By the early 1970s, though, "prestige creep" among The General's divisions had set in, with lower-zoot marques leapfrogging their betters with ballooning price tags and snob appeal; a fully-loaded Chevy Caprice could cost more than an Olds 98, a Pontiac Bonneville could out-snoot a Buick LeSabre, and the LeSabre itself came to threaten mighty Cadillac at the top of the GM pyramid. Here's a fully depreciated '73 LeSabre Custom Hardtop Sedan, once the picture of Malaise Era opulence but now brought down to earth in a San Jose self-service car graveyard. The high-rollingest of all LeSabres in 1973 was the Custom (though shoppers for full-sized 1973 Buicks really wishing to rub the noses of their lessers in their success could opt for the even pricier Centurion or Electra 225), and that's what I found among the Achievas and Cateras of this yard's GM section. Wasps now nest in the rust holes caused by rainwater seeping beneath the padded vinyl roof, but this car once told the world, "I've made it!" It went without saying that your big, comfy Detroit luxury sedan had a big, comfy front bench seat; let those frivolous rakehells in their Rivieras have their bucket seats. Believe it or not, a three-on-the-tree column-shift manual transmission was still standard equipment on the lower-level Buick Century in 1973, but all LeSabre buyers enjoyed two-pedal luxury that year. Some junkyard shopper grabbed the massive 455-cubic-inch (7.5-liter) V8 — rated at 225 horsepower, due to Nixon's stricter emissions standards and the switch from gross to net horsepower ratings — before I got here. I'm guessing this car got driven into the ground by the early 2000s (there's a 2001 calendar inside) and then spent the next couple of decades bleaching in the harsh South Bay sun before arriving here. So good, shoppers bought them sight unseen!

Automakers' sound systems: Crank it, don't yank it

Years ago, one of the first things most music lovers did after buying a new vehicle was drive to an aftermarket stereo shop to get the crappy stock components swapped for better gear. And you'd typically get not only better sound but also more bang (and boom) for your buck. But in the past decade or so, the overall quality of OEM audio has dramatically increased, while car electronics became more complex, removing the incentive for most new vehicle owners — and all but the most hardcore DIYer — to start from scratch. In 2010, I did a comparison of the average costs for OEM electronics vs. similar offerings from the aftermarket, and back then automakers' stock premium systems were by far the best bargain — and are probably an even better value now. The premium 14-speaker, 1,200-watt JBL system in the all-new 2019 Toyota Avalon is a prime example of this trend. It's standard on the top two Limited and Touring trims and is available as a $680 audio upgrade on the XLE and XSE. I doubt you can even buy 14 speakers and 1,200 watts of amplification from the aftermarket for 700 bucks, much less have it all installed. And because the system is bundled with Toyota's Entune infotainment system, Apple CarPlay and a surround-view camera, removing the head unit means you would likely lose these features. Another advantage of OEMs and their audio partners is they can design the car around the audio system. In the past, automakers would typically place speakers where convenient for packaging, not for optimal sound reproduction, and audio engineers were forced to compromise. But as with the Avalon's premium JBL audio system, this is starting to change. At a recent behind-the-scenes peek for media into the process of developing the system, Toyota and Harman engineers delved into the minutia of sealing the inner panel of the front doors to create an enclosure for 6x8-inch woofers, making space in the pillars for JBL horn tweeters and extensively measuring the acoustic properties of the interior to tune the sound to the space. I'm met some creative and skilled car stereo installers, but none with a degree in psychoacoustics. The system is also the first to feature Quantum Logic Surround that creates a multi-channel listening experience from two-channel sources. And it includes Harman's Clari-Fi processing that "rebuilds key details lost" in compressed audio formats used by streaming music services and MP3s.

GM puts e-commerce shopping in car dashboards

DETROIT — General Motors on Tuesday said it will equip newer cars with in-dash e-commerce technology, betting it can profit as drivers order food, find fuel or reserve hotel rooms by tapping icons on the dashboard screen, instead of using smartphones while driving. GM's Marketplace technology, developed with IBM, will be uploaded automatically to about 1.9 million model-year 2017 and later vehicles starting immediately, with about 4 million vehicles across the Chevrolet, Buick, GMC and Cadillac brands equipped with the capability in the United States by the end of 2018, GM said. GM will get an undisclosed amount of revenue from merchants featured on its in-dash Marketplace, Santiago Chamorro, GM vice president for global connected customer experience, said during a briefing for reporters. Customers will not be charged for using the service or the data transmitted to and from the car while making transactions, he said. "This platform is financed by the merchants," Chamorro said. GM will get paid for placing a merchant's application on its screens, and "there's some level of revenue sharing" based on each transaction, he said. It is too soon to say how much revenue GM could realize from the Marketplace system, he said. The GM Marketplace will compete for customer clicks and revenue with hand-held smartphones, which offer a far richer array of applications than the GM system will at the outset. Amazon.com is partnering with other automakers, including Ford, to offer in-car e-commerce capability through Amazon's Alexa personal assistant system. For example, GM will launch Marketplace with just Shell and Exxon Mobil icons in the fuel category. The only restaurant available for in-car table reservations at launch is the chain TGI Fridays, GM said. In addition, there will be apps for parking, and ordering ahead at coffee shops and restaurants such as Starbucks, Dunkin' Donuts and Applebee's. "We will be adding more vendors," with some coming in the first quarter of 2018, Chamorro said. In addition, he said GM plans to expand integration into its vehicles of music, news and other information services. GM also hopes to use its in-car Marketplace connections to expand purchases of products and services, such as additional access to in-car wifi, from its own replacement parts business and dealer network. Customers can "expect to see more service promotions coming through the platform," Chamorro said. Reporting by Joe WhiteRelated Video:
