Buying a vehicle on the East coast...for the first time

[Dvipercop]

The title pretty much covers it. I just moved to Washington DC (kind of a forced work move) about a month ago now and am in the market for a for a vehicle. Now, I've lived on the west coast my entire life so this whole area is new to me. I've heard that they put salt on the roads in winter here and that leads to some pretty bad rust issues with vehicles here. This could be just a rumor they tell on the west coast, but it sounds legit. Anyone that has lived in this area for a while shed some light on that? Are their any issues I should be aware of when vehicle hunting around here? Any help would be appreciated.
