All my cars made after 1990 had heated seats with the exception of the Mini. For some reason I don't miss the heated seats in that car. A heated steering wheel would be nice when driving topless but the heater is hot enough to cook my fingers. So I wear gloves when it's below 60 and when I'm going topless. Not to warm my fingers but to prevent 2nd degree burns.
The first year my wife had her Rav4 she never used the seat heaters and said she didn't need them. This year, she never turns them off and loves the heated seats, but not as much as she loves the heated steering wheel.
