And for folks who haven't lived/experienced multiple climates and aren't very perceptive to how they affect vehicles, this could be hard to totally comprehend.
But examples. The wife's now 13 year old 07 Ram. Has spent 4 winters in "harsh" areas and 9 in a "gentle" area (coastal WA). Friggin beautiful, no rust whatsoever on the body and a pretty clean undercarriage ( partly due to my upkeep of that, partly to the daily pressure wash on western wa roads for 6 mo a year!)
Also, 19 year old vehicle we just bought for a commuter rig, dubbed the "snack wagon" cause the wife and kids end up eating several meals a week in it commuting to sports.
NO body rust, original exhaust system in good shape still and actually popped one of the brake calipers off that appears to be original pads or very least hadn't been off in a long time with no issues.
Compare to vehicles back in the salt belt of the US, similar effects as Alberta, 10 years old daily drivers, you wish you could trade it in before the cancer starts dropping parts on the side of the road, 15 years and your custom brown fender wells are fully developed. 20 years and you can literally feel it rusting away as you drive down the road.
There are just too many used vehicles that are from gentle climates to consider buying one form a harsh climate, IMO. Especially with ones ability to search vehicles for sale all over the continent. Once you've dealt with repairing rust buckets, a road trip and or a plane ticket for the right vehicle, if necessary, seems like a good option.
