I bought my car last April 11. Hubby dropped me off at the dealership and I was a while with the salesman as he showed me how to use all my gadgets. I left the dealership about 7ish. It was probably 45 and pitch dark. I rode all the way home with the top down...like you said, heater full blast and seats on full heat. I didn't care. I was so excited to have this car.
When I got home we got in his truck to go out to dinner and he grabbed my hand. It was freezing. When I told him I rode home with the top down he just shook his head.
Some people just don't understand. Cars are not supposed to have roofs.
