19.5k seems a little rich for a salvage title. of course the car looks pretty good for a salvage title. there are states that you can get around that ... but ... its a risk. of course the engine is worth a reasonable amount on its own ... as are the parts
I upgraded the bluetooth system in my wife's Mercedes a few years ago, and the guy who sold me the parts buys and resells old Mercedes telephone systems that are installed into the car. Seems like a pretty cool business model.
