How GM's grueling 24-hour test gets the kinks out of its performance cars

One of the biggest challenges automakers face when designing a high-performance car is making sure that it is both fast and reliable. For General Motors, any car that might be taken to the track by its owner - like the Corvette, Camaro Z/28 (shown above) and the Cadillac CTS-V, for example - undergoes a rigorous and strenuous 24-hour test by engineers at the Milford Proving Grounds, as pointed out by Car and Driver.
We've posted on this topic in the past - on a video showing the Camaro ZL1 being brutalized, for instance - but this article gives a more in-depth look at what actually happens behind the scenes... including what that poor ZL1 went through. Though the test isn't for 24 hours straight, the cars are pushed as hard as possible by some of GM's best drivers with only the brakes and tires replaced frequently.
We don't want to ruin the fun for you, but it is an interesting article that tells just some of what GM does to develop its sports cars. Check out the full article over at Car and Driver for the rest of the story.

Don Draper's 1965 Cadillac Coupe de Ville up for auction

Few have ever nor ever will embody the sheer confidence and style of Don Draper, the main character on the hit AMC drama Mad Men. But if you can't quite match his style, at least you can drive his car. Now that the series has now concluded its eight-year run, the studio behind it is selling off a whole mess of artifacts from the show through ScreenBid, a specialist Hollywood memorabilia auctioneer. There's a good 1,300 lots up for grabs, from props to costumes. But the lot that's caught our attention is this 1965 Cadillac Coupe de Ville. Don picked this car up in the fifth season and drove it until the penultimate episode. These are the wheels he (spoiler alert!) drove across the country, got repaired in Oklahoma, and ultimately gave to a kid working at the motel before making his way by bus to the Bonneville Salt Flats in the final episode. At the time of writing, bidding had reached $25,000 with four days still to go. Cadillac first used the de Ville as a trim level on the Series 62 before spinning it off into its own model line. 1965 was the first year of the third-generation de Ville, stretching a massive 224 inches (over 18 and a half feet!) long. Powering over 4,600 pounds of personal American luxury was an equally massive 7.0-liter V8 that drove 340 horsepower through a three-speed automatic transmission. The name wasn't retired until 2005 when the final DeVille (as it was styled by then) was replaced by the DTS, which itself was shorthand for DeVille Touring Sedan. Cadillac produced the last DTS in 2011, finally putting to rest a name that had, in one form or another, been used since 1949. Few cars had the kind of presence that the third-gen Coupe de Ville did, though, and Draper knew it. Or at least the show's producers did.

J.D. Power customer survey of dealers counts Cadillac, Buick as big winners

Cadillac and Buick have taken the trophies in J.D. Power's latest Customer Service Index Study examining satisfaction with dealer service. Surveying more than 90,000 owners and lessees of 2009-2013 model-year cars, the study found that those with pre-paid maintenance packages were ten percent more likely to buy their next car from the same brand.
Dealer satisfaction scores have improved overall, Cadillac nabbed the luxury segment ahead of Audi and Lexus, taking the crown that Lexus held last year. Buick keeps the mass-market dealer satisfaction win in the family, finishing ahead of Volkswagen and last year's winner GMC. The study also found that service department use of tablets increased customer satisfaction, as did "best practices" like "providing helpful advice." Who knew?
You can find details on those and more findings in the press release below.
