I went to the same dealerships as you did, and my experiences differ a little.
I think there are two parts to the equation
- Expectation of what you can get from a salesperson
- How you get the best out of your search experience
My only expectation is simple: leave me alone to play to my heart's content. Bonus if there's some advice. If I want to learn about piano, I do my own research and I come to this site. This forum community is likely going to be more knowleageable than most sales people you meet, and more neutral.
On getting the best experience, I found professional politeness and upfront frankness on my part helps. I always go straight and ask for a salesperson that can help me in my grand piano purchase, and give this person my budget and preference. I also made sure that I asked before playing on any pianos. I think most salespeople respect that you respect them first.
Based on the above, I have had pleasant experiences from Yamaha, Kawai, Steinway, and Bosie dealers. Yamaha dealer opened up an auditorium for me to play for half an hour (that room normal rents by the hour), and the Bosie dealer let me sample their most expensive grand knowing that I could only afford their uprights. In fact I came to know about Shigeru through my search for a 2nd hand Steinway. After knowing my budget, and hearing me play, she suggested that I try out a Shigeru. My SKII will deliver in 2 days!
I will be happy to share more about my search experience if you drop me a line...
