I recently test drove the Disc Sport 4 times at 3 different dealers. They all advise that the 10,000 mile service interval cost is approximately $280. That's for oil & filter, tire rotate, full inspection & software update as needed.
Unfortunately, none of the 3 dealers had one the way I want it equipped, in the color combination I want, so I'll wait until August and order the 2017 exactly as I want it.
By the way.... No rattles in any of the 4 test drives and the alleged "turbo lag" is totally over stated...and can be mitigated by driving in Sport Mode. Honestly, in routine driving it's a non-issue in my opinion.
My only concern is the navigation/technology being less than intuitive.
