From 1975 to mid 1978 I worked for the local Hammond Organ and Steinway dealer in sales. At the time one of the more popular and very well selling models was the so called spinet style "The Aurora". It had built in Leslie, as I recall it sold for $3500 at the time. The console model called the Concorde was price about $5000, you can bet not many were sold. I do remember the 2 customers who bought them, at the time they just didn't walk in and buy first time around both men were very successful business men, one was vice president of a now defunct supermarket chain and the other owned a Cott Soda distributorship.
Interesting too I once sold a Steinway to a congressman for his teen daughter. He and his family walked in on a Sunday afternoon looked at a $8k Steinway, the girl played a couple of notes on it, daddy said we'll take it. That all happened in about 15 minutes, fastest I've ever sold a Steinway.
