Have had my White Stinger w/Tinted Windows, GT, AWD, DriveWise, Red on Black interior for 8 days now. Over my Mazda6 it's night and day. Granted, the Mazda6 after 110k miles has NO rattles and is running amazingly well and smooth, etc... a problem-free car.
But as for driving dynamics, seat quality (remember my Mazda 6 is a 2014, not today's great Mazda6), how quiet the Stinger is over the Mazda, and the solid planted feeling and native driving feel of the Stinger and styling, and performance, etc... just no comparison. Amazing.
Drove my manger around this week. He is now considering a Stinger for his never work driver. He's not sure, but it's in the realm for sure. Just not sure if he is a badge guy or can live with everything the Stinger is, regardless of it having a KIA, Audi, BMW or Monkey from Mars logo on it...
