I too have a set of the MPC PRR passenger cars. I purchased a set of three at Allied Model Trains in Culver City, CA back in the late 90's. They used to have a large wall of used trains in one corner of the store. Only one car had a price tag. It was something like $35. I asked George, one of the sales/service guys if that was per car or for the set. He said the set. (Just a side note, George looked just like David Crosby...after a rough night!) I found the add on Postal Service car on the bay. I added it in tribute to my father who worked for the Post Office for many years. I also agree that the couplers are not the best and the cars are very light. I plan on adding some additional weight inside. That should improve their ride.
