Aftermarket heated seats? Cold weather top-down driving

[socratic]

I'm thinking of putting in after-market heated seats in my 01 2.7L.

Anyone tried this? I ran into a guy who said he could do it (he's got an automotive upulstory (how do you spell this?) shop. He said he could do it for about $400USD taxes included for both seats.

He showed me what he would put in. It's a flat piece of heating element that looks like a tan piece of cloth and is about 1 foot by 2 feet. The wiring, switches and installation are included in the price.

The switches are 2-position, that is, they have a High and Low setting as well as off.

If you have seat heaters, can you comment on their ability to keep you warm on a cool day with the top down? I have seat heaters in my other car. They really only heat my bum and lower back. And when I drive the Boxster with the top down, I'd usually wear a jacket if it's cold and so warmth isn't the issue. It's actually my HEAD that gets cold. And so I'm not so sure seat heaters would help me.
