Your payment is going to significantly higher, the first and second years are the quickest and deepest dive in terms of depreciation. So it's like financing a car with 0 down, then selling it after 2 years. You're going to be way upside down (if you only paid the payment and nothing over) In a lease case, your lease payment is that huge depreciation.
If money isn't an object go for it, more turnover, new cars more frequently.
