Nick, the first column in the table gives the minimum win price (318 for PR 62) and the second column gives the minimum price for the upgrades required to complete the series (658 for PR 65). Not sure what you think I've missed.

The win cost is used with the special event rewards to calculate the net garage cost and the upgrade cost is used with the special event and series costs for calculating the net 100% completion cost. The buy price and upgrade price then make the total price for players that don't win the car.
