Specs side by side
What owners say
DeVille
Overall
Sentiment is bifurcated by generation. For classic models (1950s-1970s), sentiment is overwhelmingly positive, characterized by nostalgic appreciation for their iconic styling, immense size, powerful V8 engines (notably the 472 and 500 cubic inch motors), and their status as symbols of American luxury. These are viewed as comfortable, torque-rich cruisers.
Best version to buy
For classic models, the 1966 DeVille is specifically mentioned for its 7.0L (430 cubic inch) V8 and imposing dimensions. For the problematic Northstar era, the 2004-2005 model years are identified as having the updated "coarse thread" head bolts which partially addressed the pervasive head gasket failure issue.
Known issues
- ⚠Northstar V8 Head Gasket Failure: Catastrophic failure leading to coolant loss, overheating, and engine damage. Very frequent in pre-2004 models. Frequency: very frequent.
- ⚠Northstar V8 Oil Leaks: Persistent leaks from multiple engine seals (e.g., front cover, oil pan, rear main seal). Frequency: very frequent.
- ⚠Engine Mount Failure (Front): Common failure leading to engine movement, clunking noises during shifts, and driveline vibration. Specifically noted on post-2000 models without torque struts. Frequency: recurrent.
DTS
Overall
Sentiment is predominantly positive, with a strong consensus that the final-generation DTS (2006-2011) is a highly comfortable, reliable, and undervalued luxury cruiser. Owner feedback consistently praises the exceptionally smooth ride, spacious interior, and powerful yet refined performance of the revised Northstar V8 engine. The vehicle is widely regarded as offering a compelling value proposition on the used market, providing luxury features and comfort at a low purchase price.
Best version to buy
2006-2011 model years (post-head-bolt revision). Higher trim levels (Luxury III, Platinum) are noted for desirable features like Magnetic Ride Control, massaging seats, and a center console shifter.
Known issues
- ⚠Cooling system failures (water pump, pulley, crossover pipe gaskets): Can lead to overheating; water pump pulley seizure is a known, preventable failure point. Frequency: very frequent.
- ⚠Cramped engine bay / expensive repairs: Routine repairs are labor-intensive due to tightly packaged engine, leading to high shop costs. Frequency: very frequent.
- ⚠Suspension component wear: Magnetic Ride Control (MRC) struts are noted to leak and fail, with replacements being very costly; conventional suspension components also wear but are more affordable. Frequency: recurrent.
