I'm looking for a quote on 10 units of the specified 4x4 model. Can you provide detailed options, particularly regarding independent suspension and a 500hp engine configuration? These features are crucial for our needs, so clarity on their availability and additional costs would be appreciated. Additionally, I'm interested in exploring a 6x6 version. Is it possible for your team to create this model? If so, I'd like to request an initial proposal for 20 units as well. Please include all relevant specifications and pricing details in your response. Thank you!
