GTS as a Rally Car...?

I am searching for a rally project car, and have narrowed the search to several manufactures and models. Toyota's Corolla GTS is one I am considering but not sure if one year over another makes more sense.

Does anyone have experience prepping a Corolla GTS for off-road rally racing and if so, can you give me any background as to year of car, problems encountered, advantages/disadvantages to the Corolla....

Thanx...
