Pattern size is too large for the only deco car

There is only one deco car we can place on our lots and even though more materials have been added, there is still no material we can use to make this car look better, because the pattern scale is too huge.
I set it to zero and it’s still impossible to give this car a proper paint job and it looks weird, no matter which material I chose. The plastic category would have been a good choice to add.
Also there is no option to add a material to the roof. For me, it’s unusable like this.

This is how the car looks when I place it right from the Build/Buy
