Hi Alex, when I flew out to California to take a look at the car I found that the car was repainted, it used to be yellow also the previous owner confirmed this.
The car was shipped to Asia after its build. I am still trying to find out more but time is not on my side at the moment.
Some people think it might be this car which Fujimi made a model from.
I was not able to confirm this so time will tell.
Thanks Thomas
