All AE86 are getting old and has no more rear seat/luggage space than the Japanse coupes you have discounted - 200SX / Celica IV ST185 AWD GT4 / Supra III. Celica MkII or III liftbacks, more rear seat space and huge luggage space compared to AE86, will be way too old for easy parts, IV probably is too.
Lancia Integral? Less reliable and more expensive than a Cossie?
Unless you go back to Violet GT/160J, Silvia and those early Celicas I don't think Japanese really did RWD/4WD hatches. They are more coupe than hatch so you will be into "wagons" like Subaru.
Audi A3 1.8T Quattro or same platform/drive/engine from Seat/Skoda/VW. Would that be a 5 door Skoda Octavia RS? Still too much to lose on them?
Merc C series 3 door coupe? Suspect they still have to lose lots of cash.
