I should add another factor to my post up above...
In my case, I tend to drive very, very little, and consequently the vehicle is darn fine shape, so I would end up overpaying for the use/depreciation of it. First time around, I was obligated to return the vehicle even though I could have gotten much more for it, paid off the bank, and pocketed the difference. But no matter, because instead, they bumped up the "buyout" proportionately. Time to find a new truck, and a new bank. (This was back in the wilder days when lease packages were all over the map in structure.)
There can be sort of a sweet spot in leasing where you may get more selling the car than the payoff is. In my example above, I missed that opportunity. When the lease term expired, my options were more limited.
