#11 I'm having a tough time finding out. rfenst hasn't indicated what model year he got, but Volvo didn't introduce the T6 until the 2008 model year, and IIRC, he was already talking about it at Cfest 2008, so I'm guessing he has a 2008.
The T6 model had run-flats available as an option. While standard equipment included an space-saver spare (donut) mounted inside the vehicle, some car makers don't offer a spare with run-flats, largely to save them $ (although they will usually make other claims, such as weight-savings and gas mileage differences).
With some lines, the size tire and wheel can make a difference, too. 17" was standard, and 18" upgrade was offered. Looks like a 19" might have even been available. With some lines, they don't have enough space in the well in the trunk for a bigger wheel and tire assembly, and those who spend more for the upgrade get a can of goo instead of a spare.
Guess we'd have to see rfenst's Munroney or at least hear from him.
BTW, those heated WSW reservoirs must come in handy on those frosty Orlando mornings, huh?
