I've learned to just pace myself, don't grind for hours and hours, miles and miles, unless you're racing online for run. But who does that amirite? Everyday, I try to all gold a set of missions. I'm going to get my daily workout, plus what ever I get from the missions. That's two, possibly, three cars a day. Yes, I understand I'm eventually going to hit a wall, but I'm not spending my money. By the time I gold all the missions...I'm not going to pretend I'm they guy that golds everything in my first attempt...I'll have a nice little nest egg. Tbh, unless the 70 GT-R and the S.S. Trueno they are Legendary cars, I don't really care for most of them. They don't really serve any purpose other than showing off how much grinding one has done.
