Not sure as to the VIN change over of these, but here a few other production changes that weren't included in your list:

Relay/Fuse Access Panel Length - Long vs Short
Ash Tray
Console Clock
Gasketed Quarter Panel Glass
Routing of Main Wiring Harness
Air Cleaner Box Label
Pontoons - Textured vs Smooth
Craig Radio - No Clock vs Built-In Clock
Antenna - Fender Mounted (Fixed Mast vs Manually Retractable) vs Hidden Rear Powered
Alternator - Ducellier vs Motorola
Glass Logos - DMC larger than Sekurit vs Sekurit larger than DMC

I know that there a few more that I'm forgetting...

Here are a couple more:

The routing of the engine bay wiring harness is more subtle and not the sort to be officially called out in the Concours Manual. Those are the neat ones I like to hear about.

- inline glass fuses up at the front console could be another.
- thick and thin style rims, not just dark or light grey
- angle drive inside rubber cover (just saw reference to this for the first time recently as mentioned of being part of a recall kit)
- DeLorean logo label on front corner of hood if not already mentioned
- exhaust tips
- "the holes" in the fiberglass in the vicinity of the rear speakers, viewed by removing the interior trim panels

There may not be an exact VIN break, but under the Wheels section it might be worth noting that:

The early dark gray style wheels were an earlier style casting with thinner material around the center hub of the wheel.

The later silver wheels were initially of the original thin cast type but changed later on to a new casting with an added ring of material where the base of the wheel spokes meet the center hub.

There seem to be quite a few cars out there with both thick and thin cast wheels on the same car so there was a definite overlap until the thinner cast wheels were consumed. It shoudl be possible to determine an approximate VIN range where this occurred.

Also the early cars apparently did not have the lower section of the fuel tank baffle installed. I believe there is a VIN break associated with the addition of this part (110043)

Interesting and thank you for the info, however mine is 03037 and she has the antenna embedded/on front windshield. Anyone out there can verify this? The VIN range might be different...

"Antenna
• Up to VIN 02710 ????????? — radio antenna embedded in the glass "

[Evildeli]

3004 originally had a windshield antenna too.

Parts book lists part number change for item by change in VIN #.

[GS450-Junkie]

Maybe Nick Sutton could talk about some of these variations....

Interior Variation:

Later cars (my VIN is 16793) have LIGHT gray carpet with black interior. Not sure actual VIN range. Love that combo.
