a salvage title means the car has been damaged enough that an insurance company has declared it a total. This usually will drop the resale value of the car tremendously, but this does not necessarily mean that you are getting a junker.
I had an '89 Probe GT (i miss the turbo

) that had light front end damage...body shop said it would be $4000 to fix so they totalled it. I bought the car back for $200 and fixed it myself. All vehicles on salvage titles have to be taken to a state highway patrol inspection station, where you will expect to pay about $80 if memory serves correctly (this was about 4 years ago), but the Staties will put it through a fairly rigorous inspection, and make sure that the entire car is roadworthy.
My friend's dad is a SHP (State Highway Patrolman) and he says that these inspections really are no joke. The SHPs that do them are really strict (at least in Ohio) and they don't mess around with it. If they declare it non-roadworthy you are permitted to drive it home that day, and that's it. If you are caught driving it after that day before it's been inspected they impound the car and it's likely to just be crushed.
Anyways, i'm off topic here...odds are if your state is as particular as Ohio is on these inspections the car is fine. I found a '90 turbo MR2 that bluebook was over $5k on for only $2k simply because of the salvage title. The only thing to watch out for is just make sure you know what it was salvaged for. It could have also been flooded, or caught fire, or anything else. I'd avoid a flood car like the plague, simply because you don't know what all of that water got into and shorted out.
