The Car Connection's Take

TCC’s Bottom Line
The 2018 Audi S4 balances perfectly performance with luxury in a package that's both practical and sharp. Hardly a recipe for excitement, but one that touches all the bases. The 2018 BMW 3-Series makes its strongest case in performance for luxury compact buyers’ attentions. Very expensive and still not very large, the 2018 Mercedes-Benz C-Class nonetheless leads its luxury niche with fabulous style and fantastic power and grip.
