black book has a stranglehold in the canadian market from what i've seen. my friend is a dealer and usually get the cast offs (a month old), the black book price is based on what they sell for at auction in toronto. the local dealer lowballed me and offered me 26k cdn for my 06 (a canadian car) and the 07 they were trying to sell ~$47k.
we also use a website VMR.com to check on values...
half the fun is the shopping enjoy the process
