Iso, I remember a friend got the Peugeot 405 when I was a kid. I think that car had the same wheel/tire setup I have found for this project.
Thanks HKS_TRD!
Let's have an update!
First out, I found some original scale parts (Kyosho SI-12) for the body a while ago. Kind of rare stuff.
Then some build progress. Went through the Optima pile and found some good gears and a belt. The white center gear is probably a Thorp 5022. Got it with a donor car and it feels tough! Standard gear differentials all around. Took a classic see-through-photo of the drive train.
