Evening Gents!

I wanted to solicit a little advice from you guys. I am eyeballing this truck, it's in Littleton CO right now, just came up on listing. http://www.autonation.com/denver/Ch...n=1D7HU18N75S359683&phone=3032697800

I would be trading my old truck in for it. Current estimates are looking at about $1.7K trade in value, and with that I've got squirreled away I'm looking at $4-4500 down. My bank has preapproved me for the asking value, so we'll see where the vehicle lands if I can talk them down, or if it's even worth it. I'm certainly open to looking at other trucks, and don't have a problem with walking away either if I feel they're trying to work me. What I'd like to run by you gents is do you have any tips/tricks for dealing to make sure I don't get a raw deal on the vehicle?
