Without ads it is hard. At least watch 10 a day - 300 gc/ month. WTTT gold would be good. Since you have that many cars it sounds very possible. Upgrades need depends on skill. More skill, less upgrades needed. You really have to just play it/practice. 2-3 hours with certain upgrade level should be enough to see where you at, and to see do you need more upgrades and how much. More you practice, less upgrades you will need.
