Warehouse repairs the bare minimum, which is beyond odd considering how many space/storage/materials are available there. I hope that receives an update, because it's strange having the best workshop at a church, yet you can't even have a decent workshop inside a warehouse.
I've had a car smoking before and it was repaired. The workshop in the Snyder Trucking warehouse is a machine shop which repairs body, engine and tire damage as well as replaces bumpers and door.
This. It starts off as a fully upgraded workshop, not a basic one - just look at its description on the base map. The only reason you'd need another workshop is if you wanted the explosives one too. --- XBL : Crossbit
