Cool garage and game lineup - I like dedicated cabs, especially drivers
I laid decent quality 500x500mm carpet tiles in my garage. They are sturdy but don't have an overly thick pile so machines with castors move around quite easily. Also provides an additional comfort factor, no need to worry about damaging delicate items if you rest them on the floor and if you spill anything individual tiles can be replaced. Oh and you can fit them yourself with cabs still in the garage - I moved all my machined into one corner and worked my way around, shifting cabs as I went
I sealed the floor with a PVA/water mix before the tiles went down. It's lovely out there now - more like a games room than a garage
