With the Supra being over 20 years old, it is getting more difficult to make your own individual Supra
You also get the factor that you build something as a one off and 6 months later someone has built something very similar as they like yours
I have now seen 2 Supra's very similar to mine, one in the US is pretty much a direct copy, except they didn't quite get a couple of my custom parts quite the same, but it is close enough
The problem is individuality, I think it is the limited to what can be sensibly done within usability and taste
I think it is also a cost thing, buying parts and sticking them onto your car, is relatively cheap compared to custom parts or even extensive modification of existing parts
The only true way to have a one off car is to build from the ground up and use totally custom parts, but once people see it, if they like it or parts of it, that stays in there mind when they build there own. I guess it is sometimes just an influence rather than a total copy
Individuality is costly and very difficult without some influence from somewhere.
My build I just tried to use the stock curves and enhance the stock shape, but make it more aggressive, while making it a one off by combining off the shelf parts in a way no one had done before, as well as a fair bit of custom modification
