-Maybe put the default drivers point of view slightly backwards. Compared to other vehicles, the outside and inside mirror are not fully visible. In options, I can put my standard "seat" forward, but not backwards.
-Different configurations. The current one has police lights at the front that work as hazards/indicators. However, this is not always allowed on cruise servers like TC, as a civilian. Consider making a different configuration without the police light, and maybe with normal amber-colored indicators.
-Window tint. This could look very good on this car. You could make a seperate configuration for this. For instant: One default config, one with police lights, one with tint, and one with tint and police lights.
For the tint you can choose to tint all the windows, or just the rear ones, and leave the windshield clean. You can also choose to make this tint invisible from the inside out, or make it visible, like for instance in the GG55 mod.
-And a small suggestion: Engine power. The current rpm where max power is, is also around the redline. When driven with automatic transmission, when decelerating, the transmission tends to shift down very fast, to keep the RPMs high, at the red line. If the max power could be around 5,5k rpm, that would be nice. This might not be easy tho.
I can modify these, but not recently. Now I log on the LFS official website and enter the server to download the model is very slow and long. It takes 3-5 minutes to download a model. Have you encountered this situation?
This car with tint looks good, could you make a configuration with the tint, but without the red/blue lights up front?
Also, but this may be a more complicated idea, how about a configuration with 1 or 2 small flags at the front of the car? These flags can be colored in the garage.
