I ordered mine with heated seats, but I'm in Minneapolis. I wouldn't think you'd really need them in SoCal. However, temperature is all relative. This week it's supposed to be in the lower 40's and after the winter, that feels really warm. We roll down our windows again once we're out of the 30's. When you're used to 70's all the time, 50's are chilly... So you might still want the heated seats... they sure are nice when you want them. And I've used them on the demo car up here, and they get really hot in the high setting pretty fast, you actually need to turn them down or even off after about 2 minutes.
