I second the above. Get as much in your car now because there is very little that you can modify later that will be cost effective. Sure it can be done but at a substantial premium cost. I always had heated seat but rarely used them so I did not get them in the car but little did I realize that I now like opening the top when it is cold and the heated seats would come in real handy.
Recaro seats with heated elements cost upwards of 1000 ea to purchase and install. The option I think is 750 while ordering. That is just one example.
