If you were 100% complete before this update then it should be gold neutral to maintain a full garage and stay 100% complete. Not all the numbers are in yet, we don't know the rewards for all the LTS or SE), but the estimates are something like:
 * 1,200 for all new cars
 * 900 for upgrading these cars for 100% completion
 * 600 for LTS / SE rewards
 * 700 for series rewards
 * 292 for 5 ads per day
 * 210 for daily rewards (elite)

So total cost around 2,100 and total rewards about 1,802 without taking into account level ups (at least 100 so far) and WTTT rewards (100% clubbers should be able to get WTTT rewards each week).

Of course you can save more money by not winning all the 2018 NASCAR. You only need one of them, should save 602GC.

If you can't make this update gold positive then you are doing something wrong or have only just started.
