Richard Petty Motorsports Champion Cup can earn you 232 gold just for R$. Not counting the 10gold you have to invest in upgrading the Camry Sunoco, since you get 14gold back for 50% completion Nascar All-star series just 1-2 races later. So the total ROI of the RPM CC is the best in the whole game. It will cost some time to complete because even with heavy bot-management the Daytona & Indianapolis races cannot be done unserviced, even when fully upgraded. Richmond and most other events can be done unserviced. Also upgrading the Richard Petty will take some time. My advice is to wait with updating to 6.1 untill you finished this serie at least. The Nascar All-Star Series can also be completed with the Richard Petty.

I don't think this car is going to get any cheaper, since all you need is R$. If anything it is getting more expensive/ requiring gold.
