It's hard to say, I always won every car in every special event, if the car is thought of as a free gift, with discounted upgrades, maybe that puts a different perspective on things.

I always tried to keep a minimum to allow for sales and farmed my top event (the 10 lapper being the pinnacle), my blog about how I progressed is getting old now, but may still help, see User blog:RR3 Michael P/My car garage, upgrades and progress though RR3.

Your goals are slightly different from mine: I wanted to reach the 10 lapper, have 100% of cars (full garage), then 100% series. As 100% of cars was a high goal, winning cars in special events was more important, to me. Once the 10 lapper was reached BRL was not a problem.

If I've read correctly, your goal is to prioritise cars used in career series only. Cars used in bonus series can therefore wait. Given the size of the game and the number of bonus series only cars, this maybe a good way to progress, but you may kick yourself for not winning the 'free' cars once the career progress is complete.
