2007 Cadillac DTS �€" Two-Owner, Original Window Sticker, 4.6L
Northstar V8 Why This Car Is Special The 2007 Cadillac DTS
represents the final generation of a nameplate with deep roots in
American luxury motoring. The DTS �€" which stood for DeVille
Touring Sedan �€" replaced the long-running DeVille name for the
2006 model year and carried the torch of full-size
front-wheel-drive Cadillac luxury through 2011, when the model was
discontinued entirely. It was, in many ways, the last traditional
American land yacht Cadillac would build: a body-on-frame
front-wheel-drive luxury sedan with a big V8, a long wheelbase, and
an interior designed around passenger comfort rather than sport
pretension. This particular 2007 Cadillac DTS checks several
important boxes that are increasingly difficult to find together in
a single example. It comes with its original window sticker, which
allows a buyer to verify exactly how this car was configured and
priced when it left the dealership. It has had just two owners in
its lifetime, which tells a story of careful, consistent use rather
than the kind of anonymous fleet existence that plagues many used
luxury cars of this era. The mileage is documented and actual. For
a car at this price point, that combination of paperwork and
ownership history is genuinely uncommon. The 2007 DTS was powered
exclusively by Cadillac's 4.6-liter Northstar V8, one of the most
technically sophisticated engines General Motors ever produced for
a passenger car. First introduced in 1993, the Northstar was a
dual-overhead-cam, all-aluminum V8 engineered to compete directly
with European luxury car engines of the era. In the 2007 DTS, the
base Northstar produced 275 horsepower, while the Performance
package version produced 292 horsepower. The engine's design
included features unusual for a domestic engine of its time: four
valves per cylinder, continuously variable valve timing, and a
sophisticated engine management system. It was mated to a
four-speed Hydra-Matic automatic transmission sending power to the
front wheels through an independent front suspension setup. One
detail worth noting for buyers who know the Northstar's history:
the later-production versions of this engine �€" including the 2006
and 2007 DTS applications �€" incorporated updated head bolt
designs that addressed the head gasket concerns associated with
earlier Northstar engines. The 2007 model year is generally
considered among the most reliable Northstar applications. Features

heart of this 2007 Cadillac DTS is the 4.6-liter Northstar V8, an
engine that Cadillac spent considerable engineering resources
developing and refining over its production life. By 2007, the
Northstar had been in continuous development for over a decade, and
the version fitted to the DTS is among the more refined iterations
of the design. It features dual overhead camshafts, four valves per
cylinder, and an all-aluminum block and cylinder head construction
that keeps weight manageable despite the engine's displacement.
Output in the standard DTS application is rated at 275 horsepower
and 295 lb-ft of torque. The undercarriage photos show the DTS on
the lift, and there are a few things worth pointing out to a
knowledgeable buyer. The floorpan is solid and consistent with a
Florida-region car �€" no significant corrosion, no patching, no
evidence of structural repair. The exhaust system exits cleanly
through dual outlets on each side, with quad polished tips visible
at the rear fascia. The independent rear suspensi
