Is there any way to tell from “My Cars” (or anywhere else) which cars I have driven and which I haven’t?
Searching hasn’t brought up anything, but judging from the fact that a couple of threads suggest tracking Ferraris on paper to get that badge am assuming that there is no way in-game.
At this point, I’m just trying to up my count and know that I’ve never been in a lot of my “more pedestrian” cars (and probably a few of the Forza-livery dupes and lambos).
I thought that one of the garage specs in Forza 5 was “miles driven”.
If you go to “My Cars” and click on the car you can select view history. From this you can see how many times you’ve raced that particular car. If you are trying to get the achievement for driving the Ferraris, you can use rental cars or that is what I’ve been told. I know of no what of tracking the use of rental cars.
