英国采购需求：19英寸合金轮毂、20英寸合金轮毂、合金轮辋、铝合金轮毂、汽车合金轮辋、汽车合金轮毂

I'm interested in your car alloy wheels, specifically the 19-inch and 20-inch sizes that your factory manufactures. Could you provide me with the wholesale pricing for both sizes? Additionally, it would be helpful if you could include information regarding minimum order quantities, available finishes, and any possible discounts for bulk purchases. I'm looking to explore options for long-term collaboration, so please also share your lead times and shipping terms. If any new models or variations are on the horizon, I'd love to hear about those as well. Ensuring quality and durability is key for my business, so any specifications, certifications, or warranty details you can provide would be appreciated. Looking forward to your prompt response to help me make an informed decision!
