The Probe was released as two different version in the US. One being the SE and the other a GT.
The SE had a different motor 2ltr 4 cylinder and also had a different front and rear bumber and no side skirts. As for the GT, all Probes that were delivered to Australia were the right had drive versions of the US spec GT. I think Ford changed the model designation to SV SU and ST for marketing reasons (Not sure)
