I've been approached by a convenience store owner to sell car washes at his pumps. I have a Hamilton Goldline and need a pos with a remote. The Hamilton add ons are very expensive and at this point I cannot justify the cost or payback. I checked with Unitec about their Wash Select 11 with pos and remote. Much more tolerable on price than Hamilton. I am considering buying used Unitec equipment at a cost savings over Hamilton. My question to you is, have any of you partnered with a convenience store for this type of operation? The store I'm in talking stages with is about 1/4 mile away. Thanks very much for your attention.
