It should really tell us what series it is on the identification labels (car plates) but it doesn't.
I don't think your mates car is a series II if it was back made in June 2003.
A easy way to tell if it is Hot house Green it's a series I and if it's cosmo mica then it's a series II. (That's if it hasn't been repainted)
Does he know what model it is S, SV8, SS, Calais, Acclaim, Berlina and so on.
If all else fails call the transport people ask them what it is.
Major changes introduced with the Series II include: A new high-output GEN III 5.7 litre V8 engine, producing peak power of 245kW @ 5,600rpm, is now specified on Commodore SS sedan, SS Ute, and SV8. Holden Calais and Berlina models benefit from a GEN III V8 power boost to 235kW @ 5,200rpm. ECOTEC V6, Supercharged V6 and GEN III V8 powerplants are engineered to meet strict new emission level requirements. 245kW V8s gain additional frontal rigidity from a strut brace mounted to the strut towers and spanning the engine bay.
All models feature fresh, individual interior trim treatments. Convenience and comfort features such as cruise control, front power windows and adjustable front seat lumbar support are now standard across the range, and a sunglasses holder and rear reading lamps are now standard fitment on all sedans and wagons.
Calais and Acclaim models receive the added safety benefit of active head restraints, all models are equipped with audible and visual driver's seatbelt warning, and steering column modifications across the new range assist in reducing the risk of occupant injury in a frontal crash.
Also available for the first time, a tailored, factory fitted sunroof is optional on all sedans. All wagons are fitted with aircraft-style cargo rails in the rear compartment for extra tie-down security and flexibility, and load-covering retracting roller blinds are standard fitment. Wagons have new jewelled tail lamps with a circular design theme.
The Calais now takes on a more European-accented sports persona. Stand-out styling accents include a bolder front facia with sports bar grille and hexagonal mesh inserts, black bezel headlamps, lower ride height, SS-style side skirts, 17-inch five-spoke alloy wheels, rear facia skirts and unique tail lamps. Interiors are highlighted by all-black headliner and pillar trim, sports profile steering wheel, unique facia and colour-keyed console surround and suede-finish soft fabric trim. Extra luxury touches include Caprice-style driver's seat memory settings and heated 'memory' exterior mirrors. When reverse gear is selected, the passenger-side mirror dips to show low level hazards.
Berlina models are distinguished by twin fog lamps, black lower facia mouldings and nine-spoke alloy wheels. More luxurious interior finishes include new monotone seat trim in soft velour, leather-wrapped steering wheel, handbrake and auto shifter and satin chrome highlights.
The S and SV8 now have body-coloured grille and rear licence plate surrounds and spoiler-mounted stop lamps with clear lens. Both feature new alloy wheels - five-spoke on the S, which receives larger 17-inch wheels, and dual five-spoke on the SV8 - are matched to new-specification tyres, tuned for improved handling and firmer, quieter ride characteristics. Body coloured exterior mirrors and amber indicator lenses also set the SV8 apart.
