i'm at a tune of 5552 2000 as of now. i plan to use the last two free upgrades on nitro levels 3 and 5, as these token-only upgrades are a death wish to the one who came up with that godawful idea. also, i used the free upgrades of tests 3 and 9 on top speed levels 3 and 5 respectively

also, i MAXed acceleration and handling with the 4 free upgrades from the "Extra Horses" collection.
