Upon further research..

For the 2017 season, going from my applied 3332333 to the required 5433333 will cost 335 gold. I might upgrade one of the cars now and finish the old series, at least that will give me an additional 54 gold in return (27 for the main series and 27 for the bonus series I can complete with the upgraded car). I'll have to upgrade a car in the future anyway for completion of the new series. An upgrade sale of 30% would give me about 100 gold discount which is obviously a better deal, but I do like racing these cars so I'll enjoy finishing these series now.

For the 2016 season all my cars are only R$ upgraded, so any of those will cost me more than 600 gold to upgrade for series completion. I'll patiently wait for a possible upgrade sale.
