the old mans favorite

hi all,
never done this before but i thought you lot would be able to advise me.
my father had a toyota celica xt liftback (square headlights)1981 from new and out of all the vehicles he ever owned he absolutley loved that one.He drove it as a rep for castrol for 5 or 6 years and then retired and kept the car.In that time he thaught us all to drive in it and he spent alot of his retirement driving all around europe in it.In the end the car was stolen and retrieved twice and finally stolen and never see again.(someone else obviously loved it too)...
Anyway, my dad passed away 2 years ago and looking through old pictures in our house it has sent me on the quest to get one of these cars for myself as i loved it too.
Can anybody help me find that model celica (that model only please) so i can have as good a time as my father did over the last 15 years of his life.
cheers
