EDIT: I was corrected that this lease is via GM Financial. It does appear to be a 8.1% off deal.
I presume this is the July deal
Alot of tack on fees in this deal and we don’t see the lessor or the MF charged. Poster would not disclose the dealer, somebody else figured it out and could not reproduce. Also out of region for the OP.
Here is another reference
In this case the poster claims to get 6.8% and nobody else came close – that sounds right to me. This looks like a GM financial deal, in the same regional market as OP. Probably the best comparable we can find, but short of 10%. If we assume the OP could reproduce this discount, it would be an additional savings of $1500.
