There were at least 3, probably 4, maybe 5, JPS M3's built by Frank Gardner in 1987.
#1) Early test car, ex 325i
#2) David Towe NSW, built early '87 by converting 325 Group A to M3 Group A specs, used in first round of ATCC
#3) Nick Rahimtulla WA, full M3 built just prior to Bathurst '87, now '87 JPS colors
#4) Jervis Ward VIC, full M3 built just prior to Bathurst '87, now Mobil '88 colors
#5) BMW Art Car - Jagamura Nelson - was a Bathurst car

One of these became the Sax car - I think #2 above - raced at Bathurst as ViaCard entry.

#3 and #4 were sold to Brock/Mobil, and another one or two were built in 88. Three cars raced in '88 ATCC in Mobil colors - Brock (white grilles), Richards (black grilles), Crompton (red grilles). Both #3 and #4 became Doulman/Cotter/Bob Holden/NZ, both came back here. One of the Mobil 88 Bathurst cars also became a BMW Art Car (Ken Done). Fourth car crashed at Wellington???

Others may be able to elaborate on this in more detail.
