Audi S4.
What to Check Before Buying.
The Audi S4 blends everyday usability with serious performance, making it a popular choice for drivers wanting a rapid family car or executive express. Across generations from the B5 to the current B9, the S4 has earned a reputation for strong engines and Quattro all-wheel drive grip, though ownership costs can climb quickly if you buy the wrong example. Turbocharged V6 models are generally more reliable than the earlier V8s, but all S4s demand careful inspection of suspension components, oil consumption patterns, and service history before purchase.
