埃塞俄比亚采购需求：陕汽液化天然气牵引车，码头港口卡车

I'm looking to purchase around 100 units of a 6 x 4 type tractor with semi-trailer. I'd like the units to be in a blue color. Please provide me with details regarding pricing, lead time, and any available specifications or options. Additionally, could you share information on your warranty policies and after-sales support? It would be great if you could send over any product brochures or catalogs that you have. Looking forward to your prompt response!
