Be careful about borrowing upgrades (save, buy upgrade, post time, restore) as they record the car's PR along with the time and subsequently check it! If you restore it can cause warning messages (with threats of suspension) to be displayed. I used to borrow upgrades but stopped a few months ago after receiving a couple of those warning. You have been warned! Be careful.
