gq1 vs gq2

If we assume the values of "g" & "q" to be equal, or at least equal in this dimension, then the difference is one.

Of course if you take into consideration the impact on science of the Total Perspective Vortex then 1 can be tounded out at zero in fact that means that there is NO difference.

If you consider the "toyota" effect, that "oh bugger! Nissan beat us to all coil suspension, you will find that the difference is the tail lights and in later GQ'2 an EFI 4.2. Little else I would believe, which brings me back to proposition 2

GQ series 1
Yellow gauges
Long gearbox shifter with small knob
Seating position lower
Rear lights in body only

GQ Series 2
Green gauges
Shorter gearbox whifter with a larger knob
Seating position higher (In mine at least)
Rear lights in body and bumper
Indicators in side of front guards behind front wheel
bigger brakes
different auto

pretty much the same answers you got on the dozen other places you asked.

YMMV
