Audi typically doesn’t lease well because RV doesn’t hold up. If you’re hooked on A4 its a decent deal but you can get more bang for your buck with BMW or MB.
Your deal seems fair- I would use that deal and pitch it to one or 2 more dealers within a 40 mile radius to see if there’s a bite. I would also be patient and wait until St. Patties day- some dealers might to private promotions.
