From what I have seen they all have a little bit of surface rust here and there, my CA car just has a bit less than my Southern car. This is a semi arid area with a very short rainy season. Nine months of the year its dry.

Now the rust I am talking about is tiny flecks on the bottom of the vehicle, any spots where the paint scraped or chipped away. None of them are in danger of going through, the difference I saw was how bit the areas around a scrape got.

No rain = smaller rust spots. Once a vehicle has 200,000 miles and 18 years on it you can see small differences. This is nothing compared to the guys in the road salt areas.
