I'm sorry but I have no idea what Zen Garage is meant to do. I thought it was going to be a workshop of some sort but all I see is a glorified Skaters shop where artzy skaters go to buy t-shirts, a new skateboard deck, a new pushbike or go to get those wanky Ear hole earings put in where you can put a pencil through the earlobe.

What do they do?
What cars are they meant to work on?
Much more info is needed.
