I found a very bad quality video of the 93 Targa and Barletts car didn't have the painted lip as you said - bad memory on my part as I hadn't watched it since 2006. Jim Richards was driving a Porsche 968 in the video and I think rollcages were required after 93 after some BIG shunts in the 93 Targa (300ZX, Austin Healy, 911)
I have no idea if it has had a re-spray but someone must have painted the front lip and did a dodgey repair of the front left (part of the bumper reo was missing).
i found the original delivery docket and i was pretty close:
Manufactured: 28 June 1991 (Chassis 16141)
1st registered: 12/10/1992 with victorian rego
Owner: Linfox Transport (Aust) P/L
Dealer: Nissan Australia, Burwood Road, Hawthorn
Colour Code: AH3 Burgundy
Given the colour differences with the other photos and the prang (which I intend to get properly repaired) it may very well have had a respray before I bought it in 2004.
Be great if i could see a clear shot of the wheels on Bartlet's car because I think that's the key.
Good to see there are still a good number of ADM GTR's being enjoyed and preserved
