I can imagine lots of people are wondering if it is worth spending the 5,505 required to get the 1,594 rewards in the NASCAR series before it is changed. Whilst I can't give you a definitive answer, I would suggest it is worth doing if you have the gold and time. The 1,594 rewards are soon to be removed from the game and whilst you might not have to spend 5,505 to get the new NASCAR gold rewards, I can't imagine this will be a waste of upgrades.

Alternative strategies might be to complete a series with one car from each year of the NASCAR series, upgrade only enough to get the sponsorship rewards or just collect the sponsorship rewards by buying the last title sponsorship. All of this is effectively gold that is about to be removed from the game so worth a punt on some of it.
