This page contains all (hopefully) the information you will need to decode your own VIN (Vehicle Identification Number) for a VK Commodore.
The VK VIN contains 14 digits. It can be broken down into 8 parts. See the example below
8L69KEL114556K
8 L 69 K E L1 14556 K
Part 1 is the car manufacturer, 8=GMH
Part 2 is the variant, L=Berlina
Part 3 is comprised of 2 digits and tells us the body style of the car, 69 = Sedan
Part 4 tells us the engine, K = 3.3L EFI inline 6
Part 5 tells us what year the car was made, E = 1985
Part 6 is comprised of 2 digits and tells us where the car was made, L1 = Adelaide
Part 7 is made up of 5 digits and is a unique, sequential build number
Part 8 tells us what series the car is from, K = VK
So what we have here is a 1985 3.3L EFI VK Berlina Sedan that was made in Adelaide. All VK
First Digit tells us the manufacturer
8 – GMH (General Motors Holden)
Second Digit is the model variant
Variant
K – SL
L= Berlina
X=Calais
Digits 3 and 4 tell us the body style
69=Sedan
35=Station Wagon
Digit 5 is the engine type and capacity
N=1.9ltr 4 cyl
D= 2.85 6 cyl
L= 3.3 EST
K= 3.3 EFI
T=5.0L
Digit 6 tells us what year the car was manufactured
D – 1984
E – 1985
F – 1986
Digits 7 and 8 tell us where the car was made *
H1to H4= Brisbane
J1 to J9=Melbourne
L1 to L9= Adelaide
Z1 to Z9 =New Zealand
(* Just going off a rumour here but I have been told that there were up to 4 different assembly lines in the Brisbane factory hence why it goes H1 to H4 and from 1 to 9 for the other plants. I don’t know this for sure so please don’t take it as a fact as it may be incorrect. If anyone can confirm or deny this I’d love to hear from you.)
Digits 9 to 13 are your sequential build number
Digit 14 is the model type. In this case, K = VK
