Sorry, tried searching this and it is either not working or working very slowly.
If I do a quick upgrade on a car where does it draw the upgrades from. Will it use upgrades that I have bought for another custom tune? Say I bought a turbo for a tune in Class B, is that turbo now available when I do a quick upgrade on something else in Class B? I guess what I am trying to say if I buy upgrades in a certain class will Quick Upgrade now utilize some of the items that I bought?
I hope this makes sense.
