There's a lot of variation in the US depending on where you live. In California the car can be so old the paint has all come off but there's hardly any rust on the car because the air is very dry, it doesn't rain much, temperature variation is low and salt isn't used on roads. On the other hand you can be places like Canada or the northern midwest where Temperature swings by 100F between summer and winter, salt is used heavily on roads to melt snow, rain is common during the warmer months, and humidity levels in the summer are high. This causes cars, especially those not in covered garages to quickly rust and not last more than 15 years or so before too many components and body frame have rusted away.
And meanwhile, my Highlander will be old enough to drink in a couple years, has lived everywhere from the East Coast to the Bay Area to (currently) the Great Basin, has been taken offroad on multiple occasions, has handled dozens of blizzards like a champ, and (knock on wood) is still hanging in there, even with my rather inconsistent maintenance.
So I'd say a lot of this depends on the model, and possibly the make.
