That is a really a top line unit. I occasionally look at them on RV Trader. It should last forever, without a lot of the issues of the new powertrains. It is a great unit whose previous owners have already taken the big depreciation hit.
I used to occasionally have to drive by the Bluebird factory in Fort Valley when they were finishing up the Wanderlodges in 2006 and 2007 and they just looked great.
As I understand it during the 1990's and early 2000's Bluebird was having financial problems and had several different owners and the company decided to get out of the RV business and concentrate on school buses.
Enjoy your new purchase, I am jealous.
