I am just taking a guess here, but the discrepancies between the two books could be based on a few things. One is the timeliness that they update their information with. Used car prices in the US have gone up quite a bit in the last month or so on older vehicles (say pre 2006), just because there is not a lot of supply of them. We are actually shipping down cars from Canada, even with the dollar being above par, just because there is money to be made sending a 2007 Impala south where 3 months ago there wasn't. So depending on how often they update their prices, it will affect what result you get.

The other variable is where they get their information from. One may get it from retail sources or insurance companies, and one may get it from the wholesale auctions that dealers buy from. You have to treat the guide books as just that, a guide. They are average prices across the whole country, and rusty east coast cars bring down the average over clean west coast cars, so if you are looking at a vehicle that is out of the norm a bit (ie a standard when most are automatics etc), then you have to judge accordingly. Or as I always tell people, "It's worth what someone will pay for it." If you like the car and it's in your price range then that's the one to buy. Just my $.02
