I’ve worked for C4 dealers since 2007. It has come a long way since then. The product does pretty much everything we (and our clients) have needed it to do. There are two other C4 dealers in our area who are about the same size as us, but as far as I know we’ve been the most successful, at least over the past year or two. We’re in a smaller market, and there seems to be enough C4 business to go around. Unless things change, my preference would be to always offer C4.
