Re-post of earlier advice.
If the car has a 'Salvage' or Salvage Rebuilt" title then it has been damaged in the past and the insurance company has paid off on the car and sold it for salvage. Could also apply to a recovered stolen car. This does not mean that the car was necessarily severly damaged, but insurance companies have funny ideas about economic totals. Since there is no dealer supply of repair parts to draw from, the insurance companies would have to rely on a hunt and peck search for usable used parts. This kind of love effort is beyond most insurance companies, so they opt for the totaled approach. But once a car has a salvage rebuilt title it cannot elasily be washed back to an original clean title. You can buy good Alfas with salvage rebuilt titles, but they usually don't bring as high a price as a car with the clean original title, now when you buy, or later if you sell.
All this being said, you can also buy cars with clean titles which have been hit and repaired to varing degrees but which repairs escaped the data bases (Experian - Carfax).
A good non rust car with a clean title and verified correct milage history is always preferred. A stack of old mantenance receipts is a real plus.

BTW, my insurance company refused at first to insure my Alfa, until I told them I did not want collision, just liability and comprehensive (glass breakage). Then it was all smiles and welcome aboard. For the reason they will not write collision, see paragraph #1above. This is Nationwide, FYI. I am sure you can always find someone to write collision on an Alfa, but to me it was not worth it and I will just take my chances on having no collision coverage.
Listen to what ever all your replies say. They will mostly be right on target, based on my previous experience with the BB users. Very knowledgable group in my opinion.
