Make Buffalo 4H (Gold Citizenship exclusive) an A Class Vehicle. The Buffalo STX is non-citizenship requirement car and is cheaper, and class A.

The Buffalo 4H is exclusive to Gold Citizenship at Lux. The Buffalo STX can be purchased by anyone at PDM. However the 4H is B class and STX is A Class.

The 4H is either more expensive or close to the same price, so It should also be A class, especially being locked behind Gold Citizenship.
