I use all of the books to get a feel for prices before a purchase or sale, but why does it matter in this case? If you want to use a quote as an argument, use the lowest one. NADA, KBB, Edmunds are all widely used. Needless to say, the truck is worth to you only and exactly what you and him can agree on. You're only $1400 apart so seems like the book is largely irrelevant. Plus if the guy is a dealer he has a better idea of what that thing is truly worth to him than you do. In the grand scheme of things, as in owning that truck 20 years, seems like $1400 or hopefully less is a drop in the bucket, if it's cherry, no?
I agree. So, do you think $25,000 would be a good buy on a gold 2003 LC with only 46k miles on it (the dealer is touting the low mileage as "worth the extra cost")?
