I usually don't see "en buen estado para".

It may be one of those differences among the Spanish we speak, but this sounds very natural to me:
... debes tener un coche en buen estado para poder recorrer los casi 800 km. que tiene el Camino de Santiago.

Todo depende del contexto.

Tengo un auto apto para ir y venir a ....

Tengo un auto listo (preparado) para ir y venir a ....

@Don José: That's another sentence structure, because you're introducing the purpose from the start.

·Es un coche en buen estado para circular. (We'd usually omit the purpose, as it's already said it's alright, but it doesn't sound strange.)
·Es un coche en buenas condiciones. ("...para circular" would sound awkward, as "en buenas condiciones" is explicit enough.)
·Es un coche listo para circular. (Purpose is rather indispensable to be expressed.)
