    Exclamation The Illustrated Guide To Running Production Changes (In Progress)

    Here's a definitive illustrated guide to all known running production changes. Included with each change is the approximate (or exact) VIN changeover, where known. Note that engineering test pieces that made it onto a handful of cars (typically 10-20, or even less), but were never fully productionized or generally implemented (ie - blue/maroon interiors, air deflector retaining strips, painted 'DeLorean' logo on rear fascia, etc) are NOT included in this guide, NOR are pieces strictly associated with limited edition or one-off cars (ie - Prototypes, Pilot cars, 500 Series cars, Gold Plated AmEx cars, AXI cars, Wooler-Hodec cars, Legend cars, Canadian/French-Canadian spec'd cars, etc), as the information pertaining to such is either obvious and/or is difficult to document, with some exceptions, as listed below. Frequently seen QAC changes are included. Sources of the information contained herein will be cited where available.

    As this is meant as a guide to be used as a helpful and concise resource going forward, this thread will be locked and amendable only by the custodian of said guide, NightFlyer or his assignees. Those wishing to comment on, offer corrections and/or additional information, etc, can do so in the work thread found here: Info added to this guide obtained from the work thread will be appropriately accredited to the provider of such information.

    For the record, this list is more complete, and more accurate than the Official DMCL Parts Manual, the Millennium Concours Manual, or any other known attempts at documenting all the major changes in one convenient guide.
