What owners say
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

- ⚠Cramped engine bay / expensive repairs: Routine repairs are labor-intensive due to tightly packaged engine, leading to high shop costs. Frequency: very frequent.
