I'm interested in exploring the electric van bus options that your factory offers. As a buyer based in Colombia, I am keen to understand the specifications, features, and pricing of your products. Could you provide details on the various models available, including their capacity, range, and any unique technologies that differentiate them from other vehicles in the market? It would also be helpful to know about any customization options you provide. Additionally, I'd appreciate insights into lead times for orders and your shipping capabilities to Colombia. Sustainability is a key factor for us, so any information on energy efficiency and eco-friendly materials used in your electric vans would be great. Looking forward to your prompt response with the relevant details!
