I've only been in the PW business for about 6 months now, so Im asking the same questions as you Mr. Duffy.
But, I used to be in car sales, and my experience in that has helped me in this business. My value customers who came in, knew what they wanted, and saw the value of not only the vehicle that they were buying, but also our personal service, would usually purchase the vehicle for at or above MSRP, and call and thank us profusely.
The other customer who came in with a dictionary size book of comps and other quotes, would usually talk us down 2,3,4,5 thousand dollars and then complain about the interest, and then we would get phone calls everyday, about things that were wrong with it, and it wasnt cleaned right, and blah blah blah etc etc....
My point is that valuable customers know what they want, and they want you to show them the value of your service. And if you do that, they will pay top dollar, thank you, and refer you to friends and family. Usually... hope that helps!!
