I've used the free upgrades, now I got the BMW at 1-5-1-1/1-0-1-1 for a rank of 1460 and I am doing fine. I am currently at lab 003 test 30, but I know I will not win this R&D.

I hope only a very few cars will have tokens-upgrades only. If they put them in all of the cars that will be added in the future, it will be troublesome, you cannot even play on S9 anytime soon.
