Why would you do that when that would cost you 788 and you can upgrade the PORSCHE 911 RSR (2017) for just 700 to the same level AND complete Porsche Performance Showdown for an extra 67 reward?

Now, you are technically correct for anyone that won the Aston Martin in Balance of Power, it will be cheaper than the Porsche as you had to upgrade it by at least 204 to win it. However, you'll still need to upgrade the Porsche by 750 to complete Porsche Performance Showdown and so the upgrades on the Aston Martin will still have been a waste of gold.
