Group B cars don't need to be introduced, they're alaready in GT4. I like the history idea, but not in the GT mode, maybe they could have a history of motosport mode where you choose touring, GT or rallying and then start of back when, and work up to present day races. Like I said, as an extra mode though. I'd like rallying to be expanded on, rather than have each track as it's own even, have the events done proper like the rest of the game, have a FF rally cars only event and a 80's rally cars only event ect.
