They’re quoting you $665/mo after taxes and you don’t have to pay a single penny at signing? Then yes, that’s pretty good. But I’m not sure your calculator is correct since you didn’t select Audi, so I have questions.
For reference, here’s the 2020 SQ5 lease I just signed last week in CA:
Also, make sure your MF is base/buy rate —mine in CA was .00042, so if they’re inflating it from that to .00042, then your payment is $1400 less good and therefore you’re at much less than 10.5% off MSRP
