Occasionally a commercial will want a car model for different shots that are not easy to do real. This was before digital. The first was for the car to be lifted to see under it. I had two weeks to build and deliver this model.
This was two different Toyota cars to drive around a restaurant table. They were radio controlled. All the cars are based around a kit scale so we can get tyres. Tyres are the most time consuming part of a build.
These odd cars were to race through an engine to demonstrate different oils. They also were radio controlled and raced through large engine sets.
