lol. The guy asks questions and gets blasted out his anus by you nutswingers?
He would have probably paid your asking price had you actually answered his question. The $4,000 wheels aren't rare as ffff. The reason he asked about speedo differentiation is because he probably is used to doing things right. I'm sure before you (seller) bought the rims you did all the research you could and also had a professional helping you. So why not return the favor to someone who has interest in your product?
I wasted about a weeks worth of time and about 3 people who wanted to buy something I had up for sale and I held off on the 3 individuals for someone who asked about 40 questions about it, sent me money and then told me after that it was the wrong thing and he didn't want it anymore.
