You need to MAX/PRO a decent B/A/S class car or at least MAX a car to really gain the ability to grind credit efficiently via Season 9 races or Mastery Challenges.

Anyway, if you only want 17.9k, which is actually quite a small amount of credit, you can just farm some money with Veneno (or whatever the car you have) in Mastery, it won't take long to reach your goal.
