There are a lot of problems in your scenes. Here's my suggestions/how to fix these issues.

There is no suspension in the car(s). Try making a suspension system that is simple. Increase the spring constant to strenghten the spring and increase the damping to prevent the suspension being too bouncy.

You can make axles breakable by decreasing the break limit. The break limit makes an axle break if it reaches such limit. Make sure to make all axles (except the ones on the wheels) brakes and increase the simulation frequency to at least 100 Hz.

The car looks lackluster mainly due to the lack of details in the car. Make sure to add many recognizable details, depending on the quality of the base image. You should use the HSVA sliders and the color picker to have more color variations. The door borders should be black, or slightly darker tha the car's body.

Click at a polygon and select the "Follow" option, and the camera will follow the said polygon. If you want, add an interior and a ragdoll to make the car look even more detailed. The background looks extremely plain in general, why not add content (like buildings and trees) and terrain on it?

I almost forgot this one; Add rims to the wheels for more effort.
