Better to finance rather than lease a used car. Here is why....
Unless there is a special promotion by the manufacturer to move preowned vehicles, the rates aren't good on used leasing. The bank has to assume that by the end of the lease they will get back a car that is now 6 to 8 years old, and has about 100,000 miles. That means it doesn't have much resale value left. You end up paying for most of the depreciation, but you don't get a car in the end - and would you want a 7 year old 100,000 mile car to buy out at the end.
When you lease a new car, they can assume they will get a 3 or 4 year old car with around 50K miles, and it can still be sold for 40 to 50% of the new price. You get a new car, full warranty, and basic maint is covered.
Check both what AFS ( Audi ) and People First are offering. They usually have the best rates, although some credit unions can be good too.
