For whatever reason, HDRams forum would not load for me yesterday so I had to do some catching up on this thread. Feels like I've missed an AA meeting.
I've been an independent dealer for almost 10 years so maybe I can shed some light on interest rates. Right now, because of the Fed hiking interest rates for the last year; high prime credit (720+ Eq) on a new-late model vehicle (with 3 years) means you will fall between 6-7% if you want 72+ months. If you go with a shorter term you might be able to find a credit union that will do around 5% at 36-60 months - but then you're obviously looking at a pretty big payment. I have seen that Chrysler Capital is offering 0% on 2022 Ram 1500 Big Horns, but nothing else regarding financing on 2023s or more specifically HDs. Mostly just local dealers offering lease deals.
None of us, in the used car or new car business like the rates being high. Just a year ago 0-3% was the norm for prime credit new-late model rates. The only way a dealer can bump the interest rate, as in buy the rate from the bank at a lower rate and sell it to you at a higher rate is if it is through a big national bank like Truist, Wells Fargo, BoA, Chase, etc. (Bumping the rate can also sometimes be done with mid-subprime banks but I'm referring to prime credit here). Whatever rate a credit union offers a dealer is exactly what the customer gets, its in the credit unions contract that the dealer cannot bump the rate or else the dealer will not get funded. As others have mentioned, credit unions typically are your best bet for financing a new truck right now.
All that being said, unfortunately the rates are what they are. Your best bet is either to try to pay off the loan faster to try to beat the interest or just simply refinance when rates go down. Rates will have to go down eventually but no one knows when that will be. You've got a better chance of accurately guessing the date your truck enters production on the day you ordered it than you do guessing when the Fed will tangibly reduce rates.
So if the dealer tells you your rate is at 6.5% with a credit union approval, don't think they're trying to bend you over without even buying you a drink first - it's not them, it's the Fed.
