This is not a guarantee of actual depreciation. Local weather conditions, market factors and driver performance will also impact your vehicle's actual depreciation.

2018 Audi S3 Premium Plus Sedan 4D Standard Features
2018 Audi S3
KBB.com Review
Kbb.com Expert Rating
With a base price starting around $33,000, it’s easy to load up a 2018 Audi A3 Sedan or Cabriolet convertible with familiar Audi luxury features and still walk away for less than $40K. The sport-oriented S3 and RS 3 offer sizzling performance, but at a hefty price.
The 2018 Audi A3 doesn’t have the same visual pop as a Mercedes-Benz CLA or an Infiniti QX30, and you’ll find a better price and more legroom in an Acura ILX. Although its base price is attractive, once you start piling on options, the A3/S3 can easily approach the $50,000 mark.
