[Dimis]

Carpet tile squares and a drip tray...
Particularly if in a home garage which is more for storage than engineering purposes

Less dust (I didn't believe this, but hey you live and learn...)
Warmer.
More comfortable to roll around on when playing pretend mechanic
Cheap to replace a square or two if they get damaged or soiled.
Allows you to double the room up into a party room, poker room, theatre room or any other room your little heart desired.
