This is almost exactly what I was thinking about in my head, a Production class Celica. So it is possible, just difficult.
At first, I was just imagining having a Toyota Rally car, and I originally thought about my old Corolla, but why would you start with a corolla when we all have an idea of what it has to offer.
The same question goes to why there does not seem to be many newer Civic rally cars, even if there are much greater numbers when you get into the mid 90's model years. I know I have seen 1 newer model civic in the US, but that is it.
It is just a bit shameful that the only new car you can convert into a reliable 2WD rally car is a Fiesta. I have not seen any others to date.
I agree with everyone saying that you want to have a reliable car and finish rallies. Its more fun that way, cause you get all the mileage. I was also thinking that Toyota is a reliable name, how could we make this work?
Another Idea I have is to start with a late 80's Mustang. RWD would be fun to drive, the class needs the competition and I would think there are several donor cars available for parts. I have not seen any Mustang Rally cars in Canada, and know of only 1 or 2 in the US.
Thanks for the great info guys, keep the ideas coming!
