Buy 2014 on Lot, or order 2015?

October/November, I could buy a 2014 for $2-4 thousands discount, but only high end ($45K) Crew Cabs left on lot, so I had to order a 2015 as cheaply as possible. XL with a few extras.... power seat, windows, locks, cruise control, etc... plus $2,000.... Ecoboost 3.5L plus $1700, high end tow package: class IV hitch, beefed up suspension, trailer brake controller, 3.55 differential, plus $850 total cost $36,000... they are not going to discount a 2015. Salesman let me drive a 5.0L Coyote and a 3.5L Ecoboost and what a difference.... if you are going to drive highway, never pulling anything, save money and get the 5.0L Coyote, but if you're in the city, or going to pull a trailer alot, the Ecoboost has powerful torque and that means it will pull a 6,000 lb trailer no problem. Probably same MPG, neither engine makes any sound, but the Ecoboost has acceleration that will push you into the seat, it burns rubber from a stop.... the 6 gear tranny is standard, no extra cost, has manual button so you can control which gear you want to stay in, has tow button that drops the gearing down so it becomes like a 3.73 differential.... $36,000... five years of payments... but, I used my 2003 V8 5.4 L Triton for 12 years without anything but a couple of the coils needing to be replaced besides the usual spark plugs, tranny fluid, diff fluid, etc. So I'm hoping for another great, maintenance free truck that I can use to haul the horses or sailboat to vacationland.
