Its always been that way, cars have always looked very similar between makes. I can clearly tell a Mercedes from a Toyota, but you know that Toyota is Lexus right?, and may Lexus branded cars are Toyota models re-branded right?
Ford had no choice, blame the US and the Chicken Tax for that, they had to build them as passenger vans , they then sent them to outfitter company in Baltimore that then converted them to cargo vans, Custom since stepped in and stopped that.
I am sure I have bought kits that I probably wont build, so I am thinking I should probably sell them, I dont buy kits that I dont intend on building, kind of defeats the whole purpose.
