Talk:Porsche 918 Spyder with Weissach Package/@comment-110.22.67.70-20170719075252

I'm not a very skilled driver and I failed the Porsche 911's R&D. 5 tests left and there wasn't enough time. (But won the three championships) Can I still play this? All my three Porsches are maxed. But I'm afraid if I fail the EDD, then I will just waste all my credits/cards I spend on this car. I will use triple boosters if needed. I can even max+pro every Porsche since I've got enough resources (except for this 918 cuz I don't have enough engines). And because I have bad luck on pro boxes so if I miss I won't own this car forever. I never get any rare/legendary bps I have even opened 300+ random 8 boxes and other box but no bp found. Should I still do this EDD? What is a suggested rank that I could upgrade my 918? How much Pro cards do I need? Also I have 2500 tokens will that be enough? And how much credit do I need? Do I need to use tokens so save points? Or I just risk them? Please help me guys I don't know what should I do. I don't want to waste my credits/tokens
