"My advice, if your current truck is pleasing you and in good condition, keep it, you are already 2 years into your current 0% loan, and if you buy the new truck, before you know it, it will be 2 years old and have door dings and wash scratches. I would be willing to bet that if you keep your current truck a couple few more years until payed off, you will be very glad you resisted temptation and kept it when you still have a decent vehicle and an extra 400 to 1k a month to buy more cold beverages and toys for your tractor..."
Yep, I think that's where my head is right now. I stopped by the dealer today for a little bit to scope out the lot, but, I didn't really see anything that grabbed me. I learned that Ford no longer offers the 8' bed on the Super Crew (which I have now and was looking forward to again.) The biggest surprise to me was the 60th Anniversary addition F-150 they have on the lots have the biggest employee discount right now.....almost $10k before all the other is added according to the salesman I talked to. Not really my bag.....22" tires and all kinds of stuff that I never look for in a vehicle...but that is something.
"no offense to you or any other car salesman, but all that running back and forth back and forth, would make me walk....no, RUN out the door. i'm upfront with my salesman when i buy a truck and let them know that i want their BEST price the FIRST time. no threats or anything, just try to be firm about it and stick to my word. if i don't like the offer they give me, i stand up and shake their hand and tell them no thanks and have a nice day. i never buy the first day. i ask them to put that offer in writing and ill go home and think it over. after a day or so of thinking it over, then ill come back if i like it..."
No offense taken at all..........in fact I ran me off too after 6 months of being on the selling end

When/where/how I was taught to do it was with this method and haggling the name of the day. The dealer's "best" price was usually about three offers/counter-offers in after some frustration, back-and-forth, and, some tempers. It wore me down but some people take to it and do very well at it. All of that being said, certainly not all dealers are like that. My dad trades every few years and his salesman at his small-town dealer will call him periodically with the latest offers and give the bottom dollar....sometimes he trades sometimes he doesn't but it's all good and they know he's a loyal regular customer to them who'll be in eventually.
Where I stopped today (Bankston Ford in Ft. Worth @I20) is a place we've dealt with before. I wanted to eye the inventory for a minute but a salesguy tracked me down and I thought "oh no." I told him I had an appointment tomorrow and that I was just popping-in for minute to see what they had and he gave me a little info, his card, and then told me to look all I wanted and then left me alone and no one else approached me. Nice. I'll still keep that appointment but don't think anything will come of it right now.
