Hi Timmy,seems like you're going nowhere fast with your efforts to sell your 260. Unfortunately, at your asking price, you have entered a very congested territory, not only in the Mercedes category, but many other makes and models as well.
You're so very close to the large Ch. 126 models, and even the cars of the early 2000s are nudging your asking price. As a matter of interest, I am surprised that you're selling, considering its fine (and yours) effort in the concours last year. I would probably consider maybe asking about a thousand less, and see how you fare. Regards Styria
