Ally & US Bank where to learn more

I’ve leased several cars in the passed. All leases were financed through the manufacture like Mercedes Benz financial or Toyota. After reading several comments on different threads people mention ally Bank and US Bank have great deals. How do you find out information about leasing through them and deals?

I appreciate any assistance and appreciate this site. I’ve learned a lot!!!

I think there is some tables for ally around but best source is the dealer. Have to use your charms. I dont think thise rates are published. Edmunds only has captives

Are the numbers the same nationally or do they vary by region as well? That is, can US Bank RV be different in CA than in OH?
