Buick picks top 11 highlights from first 11 decades

Buick has taken the time to highlight some of the company's personal points of pride from the past 110 years. Those include everything from the automaker's very first vehicle, the 1904 Model B, to what Buick claims is the world's first concept car: The 1938 Y Job (above). That one also walked away with the worst name for a design study.
All told, the automaker has sold 43 million vehicles through the end of last year, and those include the lusty 1963 Riviera. That model celebrates its 50th anniversary in 2013, and remains one of the brand's most iconic designs.
Of course, Buick is rightfully proud of its quickest model, too. The 1987 GNX managed a 4.6-second bolt to 60 mph in tests by Car and Driver, and it also took the honor of being one of the automaker's rarest creations at just 547 units. You can check out all 10 in the gallery above.

GM warning 800,000 owners that their cars may need oil changes more frequently than they say

The days of changing your engine oil every 3,000 miles are long gone thanks to most cars having automatic oil monitoring systems, but about 800,000 General Motors vehicles apparently have incorrect monitoring software that is leading to premature engine component wear. According to Autoweek, certain 2010-2012 Buick LaCrosse, Regal, Chevrolet Equinox and GMC Terrain models equipped with 2.4-liter four-cylinder engines could be going too long in between oil changes resulting in a higher-than-normal number of warranty claims for the engine's balance chain. The balance chain links the balance shaft to the crankshaft, and a worn one can produce higher noise levels.
As a fix, GM dealers will be reprogramming the software for the monitors in an effort to reduce the interval between oil changes, which varies based on driving habits and conditions. Through February 2015, the software update will be done at no cost to vehicle owners, but since this is not a recall, after that point, it will be up to the discretion of dealers as to whether or not they will charge for the service. What isn't immediately clear is whether GM plans on giving assistance to out-of-warranty customers who are experiencing engine issues from the worn chain.

Opel Cascada is Europe's Buick convertible [w/video]

As we reported earlier, there has been much speculation regarding a Buick convertible of sorts. The most ringing endorsement of this conjecture comes today from General Motors Europe, as the new Opel Cascada has debuted on the interwebs. Opel calls the four-passenger Cascada an "athletic, glamorous midsize convertible." With a length of 4,697mm (185 in.), the Cascada is as long as an Audi A5, to which GM has said it would be slightly larger.
The Cascada, which is Spanish for waterfall, features a cloth convertible top that retracts in 17 seconds and at speeds up to 50 km/h (31 mph). The Cascada features a 1.4-liter turbo gas engine, 2.0-liter turbodiesel with 165 horsepower and a range-topping 1.6-liter turbocharged Ecotec engine that puts out 170 horsepower and 280 Nm (207 lb-ft). Power is sent through either a six-speed manual or six-speed automatic transmission.
According to GM, the Cascada will also come rife with luxury and tech features. In addition to adaptive forward lighting and ergonomic heated front seats, the convertible will feature Opel Eye, which is a front camera that can recognize traffic signs and incorporates lane departure warning and forward collision alert.
