MotorFiesta 1 can be completed R$ only. in fact you may not need to apply all the R$ upgrades during the event. See the relevant tips page for details as well as comments. The best course of action would be to have the car in garage before sale starts.

You will of course lost discount on R$ upgrades. unless that matters it will be best complete the event before sales.
