Maybe I'm getting stressed out over not much:
Say the loan principal is $100,000 over 72 months.
At the current 1.49% interest, that's $1,485/mo ($4,598 total interest)
If the rate rises to 2% interest, that's $1,507/mo (+$22) ($6,203 total interest)
If it rises to even 3% interest, that's $1,553/mo (+$68) ($9,394 total interest)
Probably not worth worrying about, really - but still annoyed about, because that's still an extra $1600-4800 in interest over the 6 years...
My guess is they will make it 2.49 as it currently for 75D.
I have also seen people at my work finance from Auto Loans for New Vehicles | Financial Partners Credit Union | Southern California since they seem to have good rates (1.99 or something like that). I was planning to look at them if I couldn't get 1.49 rate. May be give them a look and see what they quote you.
