Difference in running costs of those cars cannot be that big, maybe only in engine, but simply I'm not familiar with MR cars engines, so I don't know. But transmissions for sure similar, also in R5 case no need to have manufacturer engineer on events like someone mentioned before.
Also those MR cars might be good and already developed to some level on gravel, but tarmac is completely different story and many countries in Europe have events mainly on tarmac.
