Talk:Porsche 918 Spyder with Weissach Package (Enduro Double Down)/@comment-28856025-20170720180300

I have formulated my own strategy: with the car upgraded to 5555 0000 0808 (S1684), on the first invitation, start doubling after Challenge 4 (Ace Race) and keep doubling until after clearing Challenge 36 (Ace Race). Save. 34,330 EP is earned.

After that, start over at Challenge 1, start doubling after Challenge 4 (Ace Race), and keep doubling until after clearing Challenge 24 (Ace Race). Save. 12,070 EP is earned this way. Repeat twice to get 36,210 EP for a total of 70,540 EP.

On the fourth (and perhaps last) invitation, start doubling after Challenge 4 (Ace Race) and just keep going until you beat Challenge 18 (Ace Race). After beating Challenge 18 (if you have at least 69,110 EP), your points are automatically saved and you get the car.

Good luck!
