The STS was the big brother to the CTS and offered higher levels of
luxury for about 1 new Kia more in MSRP. The V version of the STS was more
expensive and used a Cadillac engineered Northstar V8 instead of the
Corvette-sourced LS series V8 that powered the CTS-V. Find this 2006 Cadillac STS-V offered for $15,000 in Detroit, MI via craigslist. Tip from FuelTruck.
From the seller: Only trades would be for property with a pole barn with electric, or a house with garage, with electric and basement. This STS-V is equipped with a few aftermarket parts from a company called TimmyC.
The 4.4 liter Northstar LC3 V8 originally made 469 horsepower and 439 ft-lbs of torque with the aid of a Roots type supercharger and water-air intercooling (maybe a few more with the aftermarket parts). From the factory the V8 was covered with all sorts of plastic shrouds and resembled a dishwasher, but this one has been de-plastic’d and some parts painted red for emphasis(?).
