I'm hoping to understand this a bit more as I'm trying to lock down financing before taking delivery in the next few days. I'm looking at the lease numbers in my application, and I'm noticing a Sales Tax line item under "Additional Charges" that seems to increase as I increase my Amount Due at Signing and lower as I decrease my Amount Due at Signing. My total cost of vehicle remains static and it seems a bit unintuitive that my one-time sales tax increases if I'm increasing my drive-off amount? I see a similar line item on paperwork for my lease of another vehicle, so I'm just trying to understand this a bit more. Can anybody help?
