This is what dealerships were originally... But then Jim Moran had the idea of having inventory on the lot and he made a killing. People want what they want, now. In theory people should wait, but having worked in dealerships for the last 10 years that customer is a rarity. 

The S3 is freaking fantastic to drive and makes some big interior improvements over the A3.

The thing you will love most? When your lease ends, you will have equity in it.

Majority of A3's are in the low 30's and that is with leather, sunroof, backup camera, and starting in 2017 apple carplay.
