I'm personally a fan of a car note on a newer vehicle. That + GAP is a form of insurance.
You pay $30K for a vehicle. Cash.
Someone else pays $30K, financed at 0.9% for 60mo. GAP.
That's pretty generalized, as every situation and deal is different. This is also not taking into consideration what type of insurance policy you have.
In general though, if you have any kind of car buying savvy at all, then you should always be able to buy the car for less money if paying cash versus financing it.
There are always cash incentives. You just have to ask and be firm.
I paid cash for my 2017 6, plus I cross shopped at several dealerships. My cash price was better than anything I was offered if I was financing.
I also asked for and got a bunch of free stuff, like tinted windows, side moulding, etc., etc. It pays to ask and to not let yourself be rolled over.
