Completed the challenge in less than two days. Upgraded the car to PR 109.5, that's every cash-only upgrade (10 out of 23). I'm saving my gold to upgrade the F14, as you can win two series with a F14 which makes it useless to fully (and expensively) upgrade the 412T.

I tried to win all missions with the smallest possible margin to ensure the bots were kept down to a very easy and slow level. That makes it possible to proceed with an unserviced car for quite some time: I only serviced the car after stages 6.3, 6.5, 7.5 and 9.4.

I didn't encounter missions that were too difficult. 4.1 was tricky (don't like the Melbourne track), at stages 4.2 and 4.3 the game didn't count all the overtakes which was making life a bit difficult, but all other missions were relatively easy, probably because of the 'slow bots'.

Didn't get the rewards on the first three missions, but I noticed that the car already had some updates so I must have completed them before (can't really remember). From stage 4 and upwards I was rewarded as mentioned above, except for the last stage where I was rewarded with 60 gold instead of 25. Nice!

So completing this challenge within four days is absolutely possible, just make sure to use the slow bots/no maintainance tactics when you're afraid you're running out of time.
