This guy sells bikes like mad. San Gabriel Valley, right? They always have that same background. I find them to be generally overpriced and in worse condition than you'd think by looking at the picture. That is with the exception of an 83 specialized expedition he sold for 300 about a month ago. Go ahead and visit to check it out, he's a nice guy. But I would say also do some research and check out new bikes you can get for the same price.
P.S. If you decide to buy from him, he can be talked down.
