Is there a Factory New UMP-45 | Grand Prix?
No. The UMP-45 | Grand Prix's lowest possible float is 0.25, above the 0.15 ceiling of Minimal Wear, so neither a Factory New nor a Minimal Wear copy can exist.

UMP-45 | Grand Prix float and wear
The UMP-45 | Grand Prix's float runs from 0.25 to 0.35, which covers Field-Tested. Within such a narrow range the wear difference is barely visible, so phase and pattern matter far more than float.

About the UMP-45 | Grand Prix
The UMP-45 | Grand Prix was added in April 2015, in The Chroma 2 Collection. In CS2 it still uses the legacy weapon model.
“The misunderstood middle child of the SMG family, the UMP45's small magazine is the only drawback to an otherwise versatile close-quarters automatic. It has been custom painted with an old-fashioned racing motif.”
