I think the Aero also has side folding mirrors and keyless entry as standard as compared to the normal GPversionR.
My car was actually badged as an Aero GPX! It has Version R headlights, and the rest of the GPversionR bodykit. But suspension and mechanical wise it's a GPX.
sorry i was thinking of the gpx to the version r, ok as fas i can tell the aero series misses out on a few comfet/safety features like
ABS (anti lock brake system)
Driver's SRS air bag system
Cd Stacker
