A quick calc of latest update (which would be old soon)

Fully upgrade new cars (5): -5216GC

Complete special events, new series, flashbacks: 1029+ GC (dont know what extra GC from the kyle busch toyota camry series)

Daily ads, daily logins, Group A in WTTT (7weeks): 2682 GC

That's still -1505GC. Depending on how much levelling is done everyday, maybe a player could maintain a fully upgraded garage. You really need to be a good driver and already have fully upgraded garage to get the 300GC/week from WTTT.
