Do you use your A/C

Yes, I do...

The newest member (Demon) in my stable was bought because it had an A/C - then in the trunk, but now working fine.
Btw:
Its an A/C by YORK; this device was common in Swiss made A-Bodies.

Driving with open windows is ok and I like it, but when you're stuck in a traffic jam, I'm glad to have A/C.
