I just noticed that some of the cars have a fully working odometer that actually track your total mileage on that car...love it!! Makes you feel like you own the car and feel bad about leaving an expensive machinery in the garage un-used! LOL!
That feature is even better done in Dirt Rally 2.0 and extends to beeign able to buy used cars in cerrer and wearing off parts just by driving.
I have noticed that in some cars but I think it resets when you finish and then use the car again, that has been my experience anyway. Speaking about the fine details, would be nice if at some stage some of the octagonal shaped tyres on racks in the pits and in the tyre walls at some tracks could be looked at once all the major things have been sorted.
