I need a design for 2 vehicles Transporter T6 and a white Tesla Model 3. The company is called Weldex. The website URL is weldex.swiss
It's a company mostly focused on solar projects. We don't have any idea. Perhaps it would be good to have one simple design across all vehicles where the Transporter can be upgraded and keep it minimalistic on the Tesla. We would like a QR code to be included somewhere in the design, I will provide that.
I'll include something we were considering for the Tesla, perhaps the logo on the door or something like that, but you are professionals, you know better than we do.
