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!

Question of the Day: Best recipient for supercharged GM V6?

The good old Buick V6 engine was built from 1961 through 2008 (including a decade of production by Kaiser-Jeep) and went into way too many General Motors vehicles to list here. In 1991, the supercharged version of the 3800 was introduced, with a Roots-style Eaton blower on top, and now you can find these engines in just about every junkyard in North America. The 3800 shares a bellhousing pattern with the also-made-by-the-zillions GM 60° V6 engine, which means that it will install (with varying levels of sledgehammer clearancing and/or axle mix-and-matching) into plenty of GM vehicles that never received the 3800 from the factory. That means one thing: engine swaps! An excellent example of this is the 1992 Chevrolet Lumina APV "Dustbuster" minivan, which is a fully caged high-performance road-racing machine that features a supercharged 3800 and 5-speed manual transmission under its long, vacuum-cleaner-snout-like hood. The RaceVan, in Springfield Monorail livery, will compete this weekend at the Michigan 24 Hours of LeMons race with Autobloggers Mike Austin, David Gluckman, and Alex Kierstein at the wheel. My personal choice for supercharged 3800 power, though, has to be the Cadillac Cimarron, preferably the not-so-sought-after Cimarron d'Oro Edition. Some bashing and welding and cutting and pasting and this lightweight Cavalier sibling could have well over double its original horsepower. So, what's your blown 3800 engine-swap choice?

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.
