I'd try buying them, fixing them up, and reselling them myself if I had the skills and capital. Why not? There have been businesses here in Mississippi that rebuilt first-generation Broncos and Suzuki Samurais. (The latter are popular with motor home owners as tow-behinds or "dinghies.") My preference would be to give Grand Marquises and Crown Vics a mild customization to make them more like Marauders. With the supply of fleet Crown Vics soon to dry up, perhaps there is also a market for Grand Marqs as taxis?
