I picked up a 1/32 scale ecto 1 at walmart made by jada toys. I have always wanted one, but have never been able to find anything remotely close to the 1:43 scale at a reasonable price. This was $6.
They said 1:32, however side-by-side with Road Champs 1:43 police cruiser you can see its size is very close. I took the light bar apart, and put micro flashing LEDs in it, 4 in total. I hope to install headlights next.
Total cost, $10.
That is actually a mechanical pencil with one of the micro-LEDs sitting on the lead.
