The short answer
Based on available data, the Chevrolet Impala comes out ahead of the Chrysler Sebring on power. Check the specs table and owner sentiment below for the full comparison before deciding between the two. Both are covered by real owner reports on CarWizz.
Overall
Owner sentiment is highly fragmented across generations, with no single dominant consensus. For classic models (1959, 1963, 1994-1996 SS), sentiment is overwhelmingly positive, centered on iconic styling, collectibility, and performance (e.g., 409 V8, LT1 V8). For the mainstream front-wheel-drive generations (circa 2000-2016), sentiment is mixed to negative, dominated by discussions of mechanical failures, poor reliability, and high repair costs.
Best version to buy
1994-1996 Impala SS: This generation is consistently highlighted as a desirable, powerful, and iconic collectible. The 2014+ generation is also singled out as the best modern version for its refined driving dynamics and quality.
Known issues
Overall
Overwhelmingly negative sentiment across the community. The Sebring is consistently described as one of the worst, most unreliable vehicles ever produced, with frequent mentions of it being a "pile of shit," a "dumpster fire," and the "reigning POS" in the Chrysler lineup. This reputation is attributed to widespread mechanical failures, poor build quality, and a general lack of durability.
Best version to buy
The 1995-2000 coupe variant is identified as the best version. It is noted as being a completely different vehicle: a rebadged Mitsubishi Eclipse with a Mitsubishi-built drivetrain (2.4L I4 or 3.0L V6), which is considered significantly more reliable than the later Chrysler-engineered models.
