Ultimate. There is a loaded word. For me, it brings to mind a 3,000 square foot garage with high performance floor coatings, a pair of lifts, a dedicated welding bay, loads of tool storage, a kicking HVAC system, and compressed air available in each work space. Of course, there would be a trolley system to move heavy junk (I like heavy junk), and workbenches that could handle the weight of Dana 60 axles and engines.
For someone else, ultimate might mean a darkroom in the basement with a 12 foot sink, and the capability of printing 4×5 negatives to 20×24 prints. Of course there would also be great ventilation and a sound system to let the user jam out while printing.
