You’re trying to reduce multi-variable calculus to algebra.
- what Cody said: different captives cut their tiers differently, many have more than 3 tiers. And:
- they don’t all use the same scoring model. (e.g. FICO Auto v8 vs Auto Enhanced Equifax) And:
- Captives don’t all generate their chosen scoring model using the same bureau. And:
3a) some captives that agree on a scoring model and what scores align to what tiers, don’t even use the same bureau in every region (eg they may use Experian in NE and Equifax in SW)
3b) Big bank captives (Chase I know, but I believe BofA also) have internal scores for their clients that can be used instead of standard score. If Land Rover’s Tier 1 is 720, you are a 700, but you’re a Chase Private Wealth client, they can use that to approve Tier 1.
I’m mainly curious to know about Mercedes, Audi, BMW currently. I assume a luxury brand would have a higher Tier 1 requirement than say Toyota or Ford.
You’re assumption isn’t always correct. A Honda might be tougher to lease than Maserati. Not just high-line vs not, in general it’s a matter of who puts up the money and how much metal do they want to move.
You’re missing a couple other dimensions:
Manufacturers whose captive is their own Bank (BMWFS, VWFS, Ally). Vs Manufacturers who lease through an unaffiliated bank (eg US Bank). Manufacturers whose captive is a major bank (just looking at JLR, Mazda, Subaru, who all use Chase - their tiers / stips / guidance are negotiated between Manufacturer and Bank, so e.g. your Tier 1 Subaru lease might actually be Tier 2 with Mazda).
And it changes from time to time. Appreciate what you’re trying to do here, even if it’s just a map of “clean no trade / no negative / Tier 1 rates for brand X” but I think you might be trying to reduce it a bit too far.
