I don’t mean to butt in here… but I think this thread is going off the rails (and in circles). OP, I think you’re looking for an easy answer, and trust me, I wanted one as badly as you seem to.
There is no shortcut to understanding a good deal, unfortunately. Let me be direct: you absolutely do need to look at all of the numbers — they all matter.
Total lease cost is a good comparison tool across IDENTICAL models only, as each car has different incentives, each dealer has different doc fees and rebate allowances (depending on your search radius)
Let me try to highlight this with an example:
I tell dealer A that I want my total cost to be, let’s say, 16k for an $45k MSRP car that I’m looking at. Dealer B has a similar car but the MSRP is $42k. Is 16k a good target for total lease cost on this one? No it’s not. Total lease cost could be 15k at dealer B and wouldn’t be a good deal. “Bang for your buck” at dealer A is higher.
Time passes and June turns to July. Incentives change. Rebates drop by let’s say 750 bucks. Is 16k a good total lease cost now? Well heck, it’s probably great if you can get it, but after adjusting for lower rebates and therefore higher Cap Cost, total lease cost on each car goes up over 750 bucks, as you now pay more interest on “more” car (and perhaps higher taxes, depending on the state)
Dealer C comes in to play and has a 45k MSRP car but WAY higher dealer fees and, for whatever reason, has 500 less lease cash available on the car in that zip code. All of a sudden, 16k sounds like a dream. Is the dealer offering you a “worse deal?” Buy rate MF is out of their control, residual stayed the same, and pre-incentive discount is the same. So what happened? 16k total lease cost now becomes “impossible” based on new incentives and market conditions. You can no longer compare total lease cost, because a “reasonable” 16k lease cost has now become “unreasonable,” yet nothing changed but for the passing of time and the captive changing their lease programs.
A little long winded reply but hope that helps.
