Where are y'all getting these crazy low lease deals?

Decided to explore my options based on some of the posts here - monthly payments in the mid $200s/month. Went in with the notion to not put anything down on a lease (per this sub's suggestions) and just try my current (well paid off) 2014 Mazda 6 as a trade-in.

Finally got the numbers run - something like $750/month or put $16k down to get to the monthly payment I wanted. I'm in no rush - I like not having a car payment, but wanted to try my luck.

What am I missing? 100% prepared to accept it's not in the cards.

Thanks!
