Buick teases the next-gen LaCrosse

Buick continues to play coy about the next-generation LaCrosse, but the latest teaser hints at a swoopy profile for the upcoming sedan. While mostly just a silhouette, the teaser does provide a glimpse of the flowing roof and upward crease around the rear fenders – especially handsome touches. The rest of the LaCrosse remains a mystery. The only other part that we've seen is the Avenir-inspired grille, which features a more angular surround and chrome wings jutting from emblem in the center. Styling aside, the brand claims that the sedan is now more engaging behind the wheel thanks to a stronger, lighter chassis and five-link rear suspension. Powertrain rumors are rather vague but suggest the 3.6-liter V6 will be available when the model arrives at dealers in 2016. One thing we know for certain about the LaCrosse is that it debuts at the Los Angeles Auto Show in November. That only leaves a few more weeks for Buick to keep this mystery going. Related Video:

Watch 14 hot rides take over concept car lawn at Pebble Beach

The Pebble Beach Concours d'Elegance is an annual celebration of the beautiful, old cars that grace Monterey Car Week. But Monterey – and Pebble – features lots of newer metal, too, and that includes the concept lawn at Pebble Beach. Now, "concept lawn" isn't a totally accurate name anymore, and you'll see why in the list below. This year especially, plenty of production cars can be found in the area once reserved for the conceptual. Still, we're happy to see them. Here's what's featured this year: Alfa Romeo 4C Spider Audi R8 BAC Mono Bentley EXP 10 Speed 6 BMW 3.0 CSL Hommage R Buick Avenir Galpin-Fisker Rocket Speedster Hyundai HCD-16 Vision G Coupe Icona Volcano Infiniti Q60 Lamborghini Asterion LPI 910-4 Maserati Ghibli McLaren 570S Rolls-Royce Wraith By our count, that's seven concepts out of fourteen cars. But it still makes for one hot group of metal. Check 'em out in the gallery above.

Neil Young to auction model train collection, classic cars

LOS ANGELES — Rock singer Neil Young is selling some of his most prized possessions — part of his model train and classic car collections. The Canadian folk-rock star is putting more than 230 of his vast collection of Lionel trains and some of his cars up for auction in Los Angeles in December. Some of the trains have estimated selling prices of up to $9,000, Julien's Auctions said on Thursday. Young, 71, known for his Woodstock-era songs as well as "Ohio," "Heart of Gold" and many, many others, has been a passionate model train enthusiast for more than 20 years. His collection and vast layouts at his California ranch took off in the early 1990s as a means of connecting with his son Ben, who has cerebral palsy, Young said. Young is also selling some of his classic car collection. They include: A first-in-production 1953 Buick Roadmaster Skylark convertible 50th anniversary special edition, with a steering wheel hub saying "customized for Neil Young," that has a pre-auction estimate of $200,000 to $300,000. A 1954 Cadillac Fleetwood Imperial eight-passenger limousine (estimate $30,000-$40,000) with the Cadillac crest styled "Broken Arrow" emblem on the rear passenger door, referring to both the Buffalo Springfield song and his ranch of the same name in Portola Valley, Calif. A 1948 Buick Roadmaster Hearse built by Flxible (estimate: $8,000-$10,000) used by Young and his band, The Squires, to haul equipment to gigs in the early 1960's. Dubbed "Mortimer," it's decorated with backstage passes and bumper stickers, and it inspired Young's song "Long May You Run." A 1941 Chrysler Series 28 Windsor Highlander two-door, three-person coupe (estimate: $15,000-$20,000), considered Chrysler's most prestigious model in its day. (For a closer look at Young's lifetime interest in cars, here's a New York Times interview from 2012, which includes an anecdote about the time he ate road tar. Or his memoir "Special Deluxe: A Memoir of Life & Cars," in which he recounts every car he ever owned, and describes how he wrote the lyrics for "Like a Hurricane" in the back of a friend's 1950 DeSoto. He promoted the book in this NPR interview. He also tipped us off to the return of the Lincoln Continental, and is known for his LincVolt plug-in biodiesel 1960 Lincoln.) As for Young's train collection, he designed a remote control that allows multiple trains to run at once, and a device that delivers realistic railroad audio to help his son get the most of out the hobby.
