maybe the "s" stands for salvage ????
Jokes asides I can not comment on the value either. But I have owned a salvage vehicle before and they can be great cars - the one I bought had zero issues and I stole it, but there is definately a stigma attached to a salvaged car, especially when you go to sell it. Personally I would pass and look for a clean title car even if I got less or older of a car. (which is most likely the case.) Especially with a P car. You see some of these for sale for a long time.
