Leasing is a 36 month loan with no asset at the end. Like any loan, the way to reduce the “cost” is to reduce the principal, either by putting more of a downpayment or choosing a cheaper vehicle. That’s literally all the flexibility Tesla gives you.

I know you keep repeating you’ve decided on leasing a Tesla, but some things to consider you may not be aware of:

1. Unlike most car companies, Tesla sales reps do not negotiate . You can’t finagle a better deal on the money factor or other games you can play with traditional dealership sales reps like playing dealerships against each other
2. unlike most car companies, Tesla leases do not allow you to buy the car at the end. In this sense it’s less of a lease, and more rental. You’re renting it, paying more than the depreciation, assuming all the risk, and have no buyout option as the leasee.
