Question re. Leasehackr Score

I’m on a learning curve and hoping someone can explain this. Why is the Leasehackr score based on the MSRP rather than the negotiated sale price? Thanks.

Because residual values are based on MSRPs. Rebates and incentives are different on purchase vs. lease

I knew there was a logical reason. I’m glad I asked. Thanks, mberbic!

It is a misleading number like the 1% rule.
