@Overlord: The color. ;) The original is black walls. The roof is new too. Also the lines haven't changed, those aren't from the Parking Lot Roads (then cars would park there, which doesn't really make sense). It's a texture change with a different corner piece. :)

What exactly changed apart from the vanilla parking lines were replaced by badi_dea's parking lot roads? :) a.k.a. what is "lighter" in this case? Thanks

Good stuff!
