BMW M5 CS is a good option for tempest 3 tier 4, It will beat all challenges without being fully maxed. Assuming you have full fusions you will need some stage 6s to beat the final challenges of 260mph and 1.36x 0-60 sprint. However, it can easily beat the final boss run time of Donna and take her Ferrari F50 from her.
The limits of PP ranges are 625pp, 630pp, 640pp, 658pp and then maxed 671pp.
This prestige cup car and former milestone car is a great opportunity for a newer player to build a tempest 3 tier 4 car. That being said, this is not a great sprinter car, so I would not necessarily use it for tempest 2.
