Well yes and no. The opportunity lost cost is 400GC if not having the car means not even getting into group C.

I used this logic to upgrade cars when I was building up my WTTT garage. Each week I would spend 100 upgrading a car in the current set. Eventually, I started to need less upgrades as the same cars came around again and were fully upgraded or upgraded enough.
