Audi A5 Sportback- Prestige Lease Deal Suggestions

Can I know what would a good deal look like? I am looking for a 3 year lease

Unfortunately, the sportback does not lease well at all. But to start, you will need to find the money factor, residual and any applicable incentives. Start here to get that info:
Next, figure out what would be a realistic discount for the car you want. Audi dealers are not going to discount the sportback as aggressively as the sedans, so be prepared. The best discounts I have seen on the sportback are around 10%/11% off MSRP, before incentives. Use this information along with your tax rate and plug the numbers into the Leasehackr calculator at the top of the page to get your lease estimate. Good luck and please post your deal.
