Maybe I went a bit too high with 90 cars..more like 70-80..depending on the cars owned. Still a Cobra cost very close to probably around 100 millions to get.

Yes C-D upgrade can be obtained for free, but still need the pro parts and at the rate you get them you need to buy a lots of boxes @ 18000.
