Toyota's web site says 1.9% on CPO used cars, but I haven't read the fine print. Subaru has 0.9% on their new cars, I wonder if they (since they have some Toyota DNA) have the same kinda thing? If we borrow money, I want to pay the least amount of interest possible.
As for which bank, we have CIBC, through their Private Banking ("Private Wealth Management") service, and we usually get awesome rates for loans (the mortgage on our investment real estate is really, really low) and waiving of all fees, etc.
The best part is the special debit card that freaks the tellers out if you happen to use counter services...
