Mid 80's sometime, went to a big name Dodge dealership, wandered the used car lot. Not single price painted on windshields, all $X/mo.
Went inside, asked sales rep, 'how much is that car, cash price?'
Reply, '$x/mo'.
Re-stated, 'how much total, in full?'
Same reply '$x/mo'.
Me getting annoyed ... 'I have other financing to pay in full, now what is the full cash price?'
'We don't do that.'
I left.

Got a new CC a month or two back. Promo rate, 0% interest for 15 months. I've put some bigger stuff on there in recent weeks. I have 15 months to pay it off at no cost to me. No end balloon either. I'm using stuff today I haven't even made the first payment on yet. I could have bought it all in cash, with a check, or on an existing CC to be paid off at the end of the month.
This allows me to add extra to the tractor loan to pay it off earlier and save interest.
