It all depends!
Forida has really cracked down on salvage cars in general. You can blame in on a number of things. One serious issue comes from the plaintiff bar. You see, there have been people injured in rebuilt wrecks. Since the shops or individuals that rebuilt the wrecks don't always have deep pockets, the plaintiff lawyers instead go after the insurance company that originally paid out on the claim, but did not consider the vehcile "no-rebuildable". They then sue the insurance company for the injuries resulting to the current owners of the car because somebody cut corners on a "rebuildable" wreck to make a few extra bucks.
There are degrees to "salvage vehicles". There are "rebuildable", and "non-rebuildable" cars. To be declared a total loss at least in Florida, the cost to repair has to exceed 80% of the value of the car (this is just a guidline). Depending on the severity of the damage, the insurance company can decide if they want it sold as a rebuildable, or non-rebuildable. Obviously the rebuildable cars bring more money at auction, because the non-rebuilds are more or less parts cars.
Here comes the problem. YES, you can wash a title from one state to the other and create an otherwise clean title. However, if that car is EVER brought back to the state that originally issued the salvage title, it can not be registered.
So, do your homework, find out where it started out as a "salvage car". The truth is, as long as you are getting a reasonable deal on the car, and understand you must pass that same deal on to any future buyer, then you will be fine.
Good luck!
