What owners say
TLX
Overall
Mixed to positive sentiment for competent luxury sedan regarded as safe conservative choice offering Honda reliability and value proposition, praised for comfortable plush seats sinking driver into cushioning, spacious trunk and adequate rear seat space (contrary to common criticism), torquey smooth engines delivering effortless acceleration, impressive wide stance creating commanding road presence, attractive interior design avoiding generic touchscreen slapping, premium ELS audio system, and exceptional longevity enabling 250,000-300,000+ mile operation when maintained. However, significant criticism centers on polarizing controversial styling (especially "beak" grille design), jerky rough transmission shifts particularly 2.4L 8-speed DCT and V6 9-speed automatic, cascading electrical warning lights triggered by weak batteries or corroded connectors creating false alarms, outdated infotainment system with frustrating touchpad interface, cramped rear headroom versus exterior dimensions, excessive torque steer (FWD models), AC compressor whining noises and failures, and questionable value proposition versus Honda Accord Touring offering 90% capability at $8,000-$10,000 lower pricing. Overall consensus indicates TLX represents competent reliable transportation and excellent high-mileage longevity proposition commanding $12,000-$22,000 used pricing (2024-2025) though lacks distinctive character, driving engagement, and luxury refinement justifying premium versus mainstream alternatives.
Best version to buy
V6 SH-AWD A-Spec (2018-2020) The 2018-2020 model years with V6 3.5L engine (290 hp), Super Handling All-Wheel Drive (SH-AWD) eliminating torque steer, A-Spec appearance package delivering sportier styling, 19-inch wheels, red or black leather interior with ambient lighting, improved 9-speed automatic transmission (versus problematic earlier years), represent most desirable specification. The 2018-2020 facelift resolved early production issues and refined driving dynamics.
Known issues

C-class
Overall
\nSentiment is mixed and highly dependent on generation, model year, and comparison context. For the W205 generation (approx. 2015-2021), feedback is generally positive, describing it as a comfortable, refined, and well-built daily driver that feels satisfyingly competent and smooth in normal conditions. It is frequently praised for offering a good value proposition in the luxury sedan segment.
Best version to buy
\nFor the W205 generation, the diesel models (e.g., 220d) are highlighted for their reliability and fuel economy, with the 2.1L diesel specifically noted for being "pretty much unkillable." The C300 with 4MATIC is also frequently recommended for its balance of power and all-weather capability. There is a strong recommendation to seek models equipped with conventional tires over run-flats for improved ride comfort.
Known issues
- ⚠\n**Declining interior build quality (W206 generation)**: Creaks, peeling plastics, and materials that do not age well compared to older Mercedes models or competitors.
