Kelly Blue Book values that van between 13-16k and these guys are only asking 11k? Plus a salvaged title?
First, it may have been a flood vehicle which you can never clean enough to prevent the amount of rust (and mold) that will come...
Second, you may have a very difficult time even registering it. You would pay a ton to get it off salvage title if you can at all.
Third, you may have a very difficult time insuring it and even if you do it will be liability only. No insurance company will pay you full coverage value on salvaged car. Sure they will take your monthly insurance payment, but if you ever filed a claim on it they would give you the value of the *salvage* (which is about $250 in my state)
If you have 10k to spend, you can find a better vehicle without all these MAJOR potential problems. There are some pretty big red-flags here
