If you keep the bots slow, you don't have to spend gold at all. You get gold and a car. You can also earn gold in the series those cars are in without gold upgrades.

Where you are in the game, $R may still be an issue. Once you get the Ferrari F40 and unlock the 4 lap LeMans race in "Classic Ferrari Showdown", after "Redline Origins" it gets easier to earn $R and gold. It's currently the most profitable race until you get well into the Legend series.
