The engines were definitely seized, but the auxiliaries are all good. ICV, throttle bodies, alternators, compressors, etc.
I saw 20-30 different cars that were definitely C4C trades. They had lime green spray paint to tell you that it wasn't permitted to pull parts off the engines. Most had the hoods up...a few were strangely missing headers, intakes, ICVs, intakes, wiring harnesses, etc.
