So the update 6.4 enables us to loan cars for the first tier and even upgrade them. As for which cars are upgradable still remains a question. My guess is only the cars in the career or main series is upgradable without owning them, not the ones in bonus series exclusively. I cannot say for sure. So this thread is to compile all the ideas or ways to use the new update features in one place. Spread the wisdom folks! ✌
