Haha, I have leather seats in my truck. I have clients with $100k + cars. Lol

To each their own coach..nothing personal but I wouldnt train at a gym that lacked basic creature comforts like yours if it was free and across the street. As soon as you said "no AC, no bathroom" I would stop listening and head for the door. I gave up working out in the garage 25 years ago.
