When is a GS a GS?

When the original sale receipt tells you it is one. If you suspect that your car is a GS but has no actual GS badges on it there is nothing on the car’s data plate that will tell you that it is a GS, unlike a GT. One giveaway is to check the wiring under the dash as genuine GS cars had the GT wiring loom to allow fitment of the GT dash and its extra instruments. If your car has the extra gauges, but a cut and shut loom, you would suspect it was not original. Unfortunately, the Ford Motor Company of Australia is not, at this time, answering queries about suspected GS cars as it is doing for GTs.
