Making a few assumptions that you farm to the limit each day, that the next update is 6 weeks, and there are no other new M$ cars. If you complete all five GP events:

Total income = 350,000 start bonus + (180,000 x 7 days x 12 weeks) + (780,000 event awards x 5)

Total income = 350,000 + 15,120,000 + 3,900,000 = M$ 19,370,000

Total spend = between MS 9,271,991 and M$ 9,571,670 (depending on car choices and strategy, PR bug not included)

Remainder = between M$ 9,798,330 and M$ 10,098,009

Since you wouldn't be able to hold on to that balance, I would guess most people could at least fully upgrade two cars.
