If this is similar to the Porsche and Corvette challenges, the expenditure in R$ was about $2 million per car (I could do the math to tell you exactly, but that's close enough). And it was 272GC per car as well. This event has a higher return in GC, though obviously it won't be a positive return. I'm sitting at 3 million R$ and 625GC right now, I figure I can get through them with that. It's not hard to farm R$ fairly quickly.
