The answer is, it depends. New vehicle financing rates are typically lower than used, so that banks can cash in on scenarios exactly like you describe. Yes, you may be able to get some incentives or what have you, but so far Ford Performance vehicles don’t qualify for any special stuff, I couldn’t even get vet. credit, because F/P vehicles were exempted. Of course, that was 2017, when MSRP was the “gold standard” deal. Now there’s negotiating room on Raptors.
If you put minimal money down and get say 5% financing new, you’ll probably have to come up with some cash to save on interest with what would in the future be a used vehicle loan. Keep in mind that even though the Raptor holds it’s resale value quite well, the amount that banks will loan out for it may not be as friendly as the resale value and that value depreciates very quickly in the first few months of ownership.
There is one advantage to manufacturer offered financing that nobody wants to think about. If you finance through the manufacturer and the worst happens; you get a lemon, one of the legal avenues lawyers have is they can withhold payment to Ford and put the money into an escrow account pending lawsuit outcome. If you finance with an outside institution, that option isn’t there. You still make the payments, but Ford, in this case, doesn’t get the money. Granted, this is not a big impact to the manufacturer, but when I sued another manufacturer, I would have gotten a great deal of satisfaction out of making those payments knowing they couldn’t have the money. stinkers.
Ford makes it very easy to win a suit against them, at least on paper, with their limited parts availability strategy. Pretty much everything on the Raptor is on “national back order” all the time. It’s not uncommon for what would be a simple part swap to take well in excess of the 30+ days required to qualify for a lemon lawsuit.
Regardless of who you finance with, choose a low interest rate and I’d suggest looking at a shorter term, not 72 months.
good luck.
