2013 Mazda CX-9 AWD with Thule summit box on top. 3.7l v6, 6 speed auto w/ manual override, heated seats/mirrors, etc. Seats 7 comfortably, I have a family of 5 plus my mom usually tags along. Decent gas mileage for size/weight. Fun to drive. Have had no problems in 8 inches of fresh snow or deep pot holed parking lots.
For real bad condition, deep snow, mud, I roll my 69 fj40 w/ chevy 350. No heater, seats two, 8 mpg, top speed 55.
I've never had heated seats, but I do appreciate the heated mirror and rear defrost on my truck. The auto AC setup is great too, doesn't blow air until it actually has heat, and backs it off once the cab is warm. I think I would take ventilated seats over heated seats honestly.
Adding to my newly acquired Subaru's accessories today, I got a $600 Yakima Skybox Pro 16 for $200 off craigslist by a guy moving to Thailand and liquidating his gear(score!):
The thing is huge though, so I have to move my Yakima bars/railgrabs all the way forward or my hatch is going to hit it when opened. Hopefully I find a good fit and it handles all my boarding gear/roadtrip storage needs.
Heated seats are great. I appreciate them in a diesel especially. Nothing like a heated seat though even outside of winter. I work for a living and the heat is real nice on the back after all the abuse it takes to pay the bills.
Last winter when I was working up north I got a ride home from the mountain from a girl with a brand new F150. She referred to the heated seat as "the beaver heater".
