The one main disadvantage I see to larger car collections (more than a handful) is the need to use each one enough that it doesn't deteriorate just from sitting (brakes seizing up, gas going bad, rubber drying out and so on). This particular collection, with so many cars parked in front of each other so that it seems like a giant puzzle if you want to get 'the one in the back' out for a drive, would be a major challenge to keep in good shape. Nice collection though.
