You can put them in yourself to learn my friend. The score doesn’t matter honestly. All it is, is MSRP divided by payment. It’s totally meaningless.
Yes used car values are insane right now, so it’s definitely not a bad idea to take advantage, but having equity is the same as having cash in your hand.
My S2K is worth about $20k trade in…should I walk into the Honda dealer tomorrow and have them pay me to lease any car on the lot?
My Accord has about $10k positive equity in it…same question, but my selection is much more limited 
Having $1,916.54 of trade equity and rolling it into a new lease is no different than putting $1,916.54 of your own money down. It’s your money. And who knows if a Lexus (or other) dealer across town would have given you more for it, let alone all of the easy online options.
Just enjoy the new ride and learn for next time 
Thank you for posting the contract to analyze!
