Wait, you live in Michigan and you have no heater in the car? The heater in my 911 works amazingly well. I drove it on the highway last winter on a night when it was ZERO. The is the only time I have had to keep the heater levers all the way up. The footwell blowers did not need to run but it was toasty in the car.
I will be driving west towards the sun while going through Death Valley in the afternoon next week. I will get to really test the AC.
