Autoblog sell-it-yourself highlight: 2013 Infiniti QX56

As Lincoln announces an all-new Navigator at this year's New York auto show, and General Motors' Arlington (Texas) plant runs 24/7 cranking out Tahoes, Yukons, and Escalades, Infiniti's big QX56/80 continues to gain fans in a great many upmarket zip codes. And its appeal – for those with an appreciation for Big Foot footprints – is obvious. Built atop Nissan's Patrol platform, the QX56 offers high levels of refinement with cubic yards of utility. Introduced by Nissan's Infiniti division in 2011, you would assume any inaugural bugs had been worked out by 2013, the QX's third model year. Power was supplied, in the press vernacular, by Nissan's proven 5.6-liter V8 producing 400 horsepower and 413 pound-feet of torque. A seven-speed automatic transmission was standard on all models, and while the additional speeds might suggest some semblance of efficiency, no one should confuse this big QX with a Toyota Prius. Our 'for sale' example, with 84,000 miles, represents above-average mileage for a 4-year old vehicle. But if those are largely highway miles in and around Madison, Mississippi, and service records are available, you shouldn't be too concerned. This is, with proper maintenance, a 200,000-mile platform, leaving you about 116,000 miles for your $37,000. And the 'ask' seems about $5,000 too dear; perhaps the seller will throw in a gas card.

Infiniti QX70 drops V8 for 2015, holds line on pricing

QX70 was the only application for the 5.0L, making it a tough sell in the boardroom.
It was always easy to chuckle a bit at Infiniti's branding of its FX crossover as a "bionic cheetah" - until you drove the thing. It was something of a revelation when it came on the market in late 2002 - certainly visually, but also in terms of performance, particularly in V8 guise. The Porsche Cayenne burst on the scene at the same time, and between the two of them, they vividly illustrated that the idea of a performance utility vehicle wasn't the oxymoron it first appeared to be.

Is your new-car warranty good at the race track?

We've all heard the horror stories. Your buddy knows a girl that was dating a guy whose best friend's brother once broke his brand-new, recently purchased performance car while making runs at a drag strip or laps at a track day, and the manufacturer wouldn't cover the repair under warranty. True story? Urban legend? Complete crap? Yes, no, maybe. One thing's for sure: Automotive warranties have always come with caveats. In 1908, an ad in the Trenton Evening Times clearly stated: "All Ford Cars Guaranteed for One Year." Although it changed over time, by 1925 the Ford New Car Guarantee only covered 90 days on material and 30 days on labor, and it clearly stated that that there was "No guarantee whatever on Fan Belts, Glass, Bulbs, Wiring, Transmission, Bands, Hose Connections, Commutator Shells, Rollers, Spark Plugs or Gaskets." Whether or not Ol' Henry would pay to fix your Model T if you broke it shaving a tenth off your lap time at the local board track seems to be lost to history. We're guessing no. But what about today? Do new-car warranties in 2017 cover cars when they are driven on race tracks? We researched the warranties of 14 auto brands to find out, and the answer is yes, no, maybe, depending on the brand, in some cases the model, and whether or not your car is modified from stock. Acura has been out of the high-performance car game for a number of years, but jumps back into the party in 2017 with its hybrid-powered $173,000 NSX supercar. And Acura's warranty, as well as Honda's, clearly states that it does not cover "the use of the vehicle in competition or racing events."

No question," he told us. "However, if the car is modified, say with slick tires or other components that would put higher stresses on the vehicle's parts and systems, then we would have to investigate the circumstances further." Marie went on to say the same would be true for any Acura model or Honda vehicle, including the new 2017 Honda Civic Si. This became a common theme. Chevrolet actually started this practice with the fifth-generation Camaro on the high-performance ZL1 and Z/28 models.
