Doo didn't offer the 4 year warranty - because they didn't have to - demand was going to be high, no OEM competition, and a two year was all that was needed to seal the deal. There's a few who didn't buy a 20k USD sled because of the 2 vs. 4 year, but for most of these early adopters of a 20k sled who upgrade almost every year, anyways, it wasn't a deal killer. When poo does it's turbo thing, and will have to offer a 4 year just like they did with the release of their 850 for all the obvious reasons they have to offer it now, perhaps doo will bump the warranty to 4. Agree with all the thinking re: no more wear than a naturally aspirated 850. With the motor essentially in warranty prison, with all the controls and markings, their part warranty costs are likely to be less than the non-turbos, at least for the common parts between the two platforms, turbo and non-turbo.
