70 dart 470 ci drag car build.
I would rather be hot and sweaty then be cold. However, I have had heat in my garage for over 20 years and about 5 years ago installed A/C. I can't believe I didn't do the A/C 15 years before that also. It is nice working on stuff and not dripping sweat everywhere. 70ish in the garage when it's 95+ outside is nice.
