In some cases it is. For example, my nissan needed 3 gold to get fully upgraded, but I can get 41 gold if I finish the series. So if you have fully upgraded cars already or only need a few upgrades this could actually result in a profit plus more playing time for you if you get bored or have finished all the other series.
