The difference in comfort packages between the touring coupe and roadster are small -- the cooled seats are cool, but nothing keeps you cool with the top down when it is 103. With the top up, the air conditioner is powerful enough that I find I don't need the seat coolers turned on -- so they are neither here nor there for me except for April and October when we have our two months of San Diego weather
. The choice between those two should be on whether you want top down motoring or the bit of extra performance you get with the coupe.
