Salam,
This project was basically a sort of restoration of a toy car. This toy car was my first birthday gift way back in 1984. Pictures below,
Allah has blessed us a son and he is going to celebrate his first birthday. I was thinking of presenting him something different if not special. I decided to DIY of restoring this car.
By now you have seen the damages to the car, front bumper, front lights, backlights, rooftop light are missing, stickers, sides broken (near bumpers), windscreen and one window glass is missing or broken.
I kicked off the proceedings with front bumper. For this I used milk can and a wall clock plastic base. Used Soldering iron and knife for plastic welding and cutting, heating for giving desired shapes.
After this I used sanding and coloring with shinny black spray.
Next I picked was front lights, initially I used bike indicators. It was unsuccessful in the end, due to heating process glass became faded and due to low quality plastic, buffing didn't work. Then I used bike helmet visor, it didn't get faded. I am aiming in future phase, to use JDMs broken lights, better quality plastic, buffing would be possible.
Beside glass work I also added background chrome, using aluminum foil.
For backlights I used bike reflectors, shaped them as per area by heating.
For rooftop light, I used a light part from a donor car.
For body damages I used filler, sourced from dent/paint shop. Used plastic, mold them as per need, glued them to the broken areas to fill that area. Applied filler for final finish.
LEDs were used for illumination, unfortunately I didn't work quiet well in the end. I didn't have much time so I decided to improve it in the next phase. For now I captured the effects in dark. Pictures to follow,
For windscreen and window, I also used helmet visor, crafted them, molded them, colored them.
For side emblems I took help from plotter (service available at any number plates shop). Result can be seen later in this write-up in final outcome pictures.
After completing all the repair work, I proceeded with color process. Used matt black for the lower base, shinny black for glass, side mirrors, bumpers, tyres. Shinny red for the body color and hardener in the end.
Now the final outcome:
That's all 
I hope you will like my effort. Thank you for your time.
