Please visit the web address www.apa.ca. If you join them for about $30 a year, you get two free quotes on new vehicles of your choice. Additional quotes are $10 ($15?) each. They may tell you the actual invoice price the dealers get from the manufacturer. Normally, they say you can get the deal for about $800 over the invoice price.
My colleague used this way and was happy with the deal. I may try to use the service later this yea.
