Yamauchi recently said that they plan to update standard cars to premium. If that happens it will most likely be limited to a few select cars. It would seem easy to remove a standard car from the used car dealership (standard) and put it into the dealerships (premium). A natural consequence would be to reset the mileage count to zero in the dealership but what if you already bought it in the used car dealership before it was updated to premium? Then it would probably change category in your garage but what about the mileage count it had from the used car dealership? Chances are that players who already bought a car in the used car dealership will be slapped because the update will make their expensive used car (with engine overhaul and rigidity improvement bills) available as brand new. On the other hand it would also be weird if they reset the cars in your garage because they were updated to premium. Especially if you drove a lot of miles in it and did pay the expensive maintenance bills. Not a huge deal but it still got me wondering how they could update this without making casualties.
