I agree with you on the seats and the steering wheel, but I do not find that my car retains the heat.

On a side note, my wife has made it very clear that her next car must have a heated steering wheel. Her car does not and on occasion when she takes my car she thinks the heated wheel is just heaven. We will go out with my car on a freezing day and I'll say, "I forgot my gloves, oh, wait no need, I have a heated steering wheel". Bugs her every time!
