Good luck everyone! While finishing Lab 1, and while waiting for Lab 2 to open, I've been grinding and now have the car at 4444 5555,  I had to use ~1500 tokens for the acceleration and handling upgrades from 3 to 4. Looks like there's 3 free upgrades across Labs 2, 3,and 4, and challenge 5 of the McLaren P1 Mastery will give me the 4th free upgrade I need to avoid spending any more tokens on upgrades. Now I just get to see if my racing skills and the remaining 2000 tokens I have left are enough to complete the R&D. I am going to have to spend a few because I'm travelling and unable to play for most of 2 days of Lab 2.
