S4 B8.544/70
The Deal
5
Book is 1.03 times the going rate for its power, so the entry is fair, and resale takes about $1,457 a year, which is gentler than the F30 335i's $2,404.
The Drive
7
A supercharged V6 whose whine is a real reason to own it without being the headline, steered through an electric rack that reads like the Golf R's: precise and numb.
The Upkeep
4
Fuel at 20 mpg and insurance at $2,295 are the two big lines, and the insurance is a model-wide S4 figure averaged over four years, so read it as an estimate.
The Risk
5
A cold-start rattle is the tell for the cheap chain fix and does not rule out the $2,500-4,000 guide job, and a binding steering column shows only on a test drive, with its repair cost unpriced.
The Daily
8
A proper four-door with a 12.4 cu ft trunk, 34.0 cu ft with the second row folded, and a dash that predates phone projection.
The Limit
6
Quattro traction under a nose-heavy V6 that pushes wide before it rotates, with the sport rear differential an option rather than standard.
The Mods
8
$520 buys a software tune and $1,698 buys the pulley and tune together, claiming about 117 more crank hp, and more boost leans on the chain and supercharger drive the Risk panel names.
