1982 Isuzu I-Mark Diesel sedan has been unexpectedly discovered in a Colorado car graveyard, providing automotive enthusiasts with a rare glimpse into the early days of Japanese imports in the United States. Finding a second-year T-body I-Mark in a boneyard is already an extraordinary occurrence, but stumbling upon one equipped with the naturally aspirated 1.8-liter diesel engine makes this discovery a true piece of automotive history.
Originally sold new at Fisher Chevrolet-Isuzu in Boulder, the subcompact car appears to have lived a modest life, featuring a base five-speed manual transmission and omitting frivolous extras like a passenger-side mirror. Evidence from old CU Boulder parking stickers suggests the vehicle spent its formative years serving as a dependable commuter for a local university student before eventually winding up abandoned in northeastern Colorado.
