Heated seats are wonderful, especially on those super cold mornings when you must get out and go to work. I try to start my car at least 5 minutes before I leave in order for it to warm up and I turn the seats on when I start the car. Toasty and nice when I get in.
I don't have them but I would love them. My friend has them and I think they are amazing! We take a shopping trip in November and they are always on. Her heater goes all the from your butt to your muddle back!
