Check your math on the FXX-K. 40% off is 570 + 993 for FU at 30% off is 1563. Winning it for free and paying full price to upgrade it is 1419.

Some people have reported being able to apply upgrades to un-owned cars in the past but it appears to be a glitch. I tried with the E-Type sale last update and wasn't allowed.
