I bought a Sapphire/Ebony Reserve AWD 2.3L, Climate, 19" Wheel MKC yesterday, pick it up Sat morning. Used X Plan, $1000 Conquest Cash, $750 X Plan Cash, 0.9% 36 month. About $3800 under sticker before TT&L. Another nice thing about X Plan is it limits all other dealer fees to a total of $100.
I also figured out the SiriusXM announcement. The MKC comes with 6 years of Traffic and Travel Link, which will stay active even if you don't continue the Radio subscription. Normally those features can only be active in addition to a Radio subscription. There was some initial confusion that the announcement was for 6 years of free Radio, which is not the case. To be clear, 1 year included Radio and 6 years included Traffic and Travel Link.
I'll report back with real world MPG and posts some pics after delivery.
