Every generation of Carinas had its GT model, including the A40 generation. The A40 generation had four flavors of GT models: the 4 door sedan and 3 door hardtop, powered by the 1588cc 2T-G and the 1968cc 18R-G engines.

This 1980 four door Carina is the kouki GT 2000 sedan, meaning it is a RA45:

The quad headlights on the GT model really look like a predecessor of the A60 headlights.

And the taillights also look very different from the normal A40:

They are darker and the reverse lights are now placed inside the moulding.

It also got lowered a bit:

These old school Work Equipe reverse really fit the Kyusha Kai style!

Seeing how beautiful the kouki A40 actually can be I would trade my TA60 for one anytime!
