This is the first time I buy a vehicle on my own, so I have no experience in this matter. Today I will be meeting someone who is selling their motorbike. I think he is asking too much for it so I want to make a reasonable offer without offending him. What is the best way to do it?
Edit:
I'm from Buenos Aires, Argentina. Maybe I didn't express my question correctly because english is not my native language. I don't really think the price is too high, but I want to try and haggle because of my own budget (The bike is U$S 4700 but I have roughly 4200 to spend). I know it's common for a buyer to try and lower the price of a used vehicle, but it really depends on the predisposition of the seller to take it as an offense or not. What I'm looking for is a way to ask for a lower price.
