That price if US seems a bit high. The base (US) price of a Bambi for 2005 is $35,553.00 without the LS package which I believe costs about $1900 retail. You can find the base price here on the Airstream site:
Typically the average discount off list is about 17%, but folks have seen about 19% in most cases. So adding the numbers, you should be closer to $30k(US) for an LS equipped 19' Bambi(plus tax, title, etc) without any trade in. Also keep a look out for dealer prep fees that are obnoxiously high with some dealers and are add profit add ons. I would pay little to no added line item dealer prep fee.
BTW, using the exhange rates as of this evening, $30k US would be equiv to $38,750.97 Canadian.
