vin559.com comments on Chestnut Fleet Rental: "88 cars …were purchased from the DeLorean Motor Company (DMC) and leased back to [Chestnut Fleet Rental], which was intended to provide early funding for DMC, and DMC in turn would get to use them as company cars for their employees. In essence, it was a loan with the collateral being 88 cars… There was an early shipment of 22 DeLoreans, then a later shipment of 66… the deal went south, and DMC never paid CFR. It got caught up in a whirlwind of legal battles, and finally CFR won the collateral of those 88 DeLoreans. The only problem? Since there were 13 unassigned company cars, and DMC was short on funds and parts, many of these 13 (Egull included) were heavily scavenged, to use those new parts for cars still on the assembly line."
