The 2019 Holiday Cup is called 12 Days of Donna. To take part you have to use these cars in any order:
- SUBARU WRX STI
- Ford Mustang GT Premium
- 2015 Nissan GT-R (R35) Premium
The reward for doing some really easy races is the the Audi R8 V10 Decenium!

I decided to start with the WRX, then the GT Premium and finish with the GTR. The event is a mix of solo races and so called relay races.
