I've had the privilege of living multiple years in Wisconsin (15), Arizona (16), Colorado (10), Washington (4), Florida (2), and Rhode Island (2).
The best conditioned vehicles are without question the Pacific NW. I shop Seattle and Portland first. The worst was Rhode Island. Believe it or not, Florida was worse than Wisconsin too. I don't think there is any significant difference between CO and AZ.
