Hi, I'm considering buying a '04 xc70 w/ 50k for a good price. It is very clean, but noticed that it was from new jersey (salt air and road salt for ice). Upon looking closer, the mechanics of the car under the hood and undercarriage look fairly clean, with some minor rust/corrosion where parts were unpainted/treated. Is this a deal breaker? How well are volvo's treated for rust/corrosion protection. should i be concerned about the longevity of this vehicle? Thanks for any help. -Bob
