Speaking of the finance office, you have a lot of room to negotiate when you get to that point in the buying process. Before you get there, you need to set your purchase price with the sales rep. Don't go into the finance office without a written price. Read these forums to see what people are paying for these things. Do not up your price in order to get lower interest rate, it will not benefit you in the long run.
My finance department knocked off the interest rate by a whole point by shopping my loan around to different banks...so they did help me there. The rate was lower than anything I found by calling banks on my own.
The finance guy has the power to remove the deductible from your platinum warranty...at no charge to you. Just ***** about how the warranties are not worth it unless the deductibles are ZERO.
He also has the power to sell it to you at a significant discount. They start at like $2000 for the 7yr/100k platinum deal. You can get it for under $1000. Find that dealer (see link below) that was offering the platinum warranty for really cheap, and then use that as a negotiating point when you buy (wish I would have). If your finance guy won't meet that price, then buy the car without the warranty and get the warranty at a later time after you have your truck from the other dealer. It won't affect the warranty price as long as you do it soon after buying, but check with the other dealer first! Here ya go:

The maintenance plan includes oil changes, but at 10k intervals. This is because the dealers now use only synthetic oil. This is normal these days. You do take it in for a 5k interval as well, where they will rotate your tires and do a few other things. Synthetic oil changes cost about twice as much as regular ones, so your value is not really sacrificed here, but you could ***** about that and get them to come down on the maintenance price because of it. Again, he has a WHOLE LOT of room to come down on that.
EDIT:
Make sure you check with your insurance agent before purchasing gap insurance or whatever it is called. I believe insures you for the difference between your insurance settlement and your loan balance in the event of a loss if it happen soon after you own it.
(End EDIT)
Most dealers charge a $399 fee for paperwork, processing, etc. Or some amount. I tried to get them to wipe this and simply could not get them to budge on that one.
All that stuff really adds up!
Good luck!
