There is not much hope for 7th Celica to be like Supra or MR2
(given the same period of time from the day it is discontinued)
Few important things for highly collectible sport cars:
1) Rarity (Production number, sales)
2) Racing Herritage
3) The car should be ahead of its time, concerning power, design, technology, etc..
4) Distinctiveness, one should be unique
Don't get me wrong, I like Celica A LOT!
It always took left my eyes from the road when I see one.
But, to be realistic.
7th Celicas are mass produced.
Hundred of thousands of them are on the streets.
They don't have racing herritage.
They are fantastic car, fun to drive, but not unique or powerful enough.
Many people buy them as daily drivers.
Truth hurts, and I hate that.
