Cadillac Delivers Excellence, GM does not.
I purchased my 3.6L v6 STS fully loaded for $10,000 after my previous Cadillac, a 2000 Deville DHS, was totaled from hail damage. I needed to get a new car quickly, and I had my first Cadillac for so long with no issues; I wanted to stick to the brand. When I first sat in the vehicle the overwhelming number of "intuitive" features was extremely intimidating. Overtime, they grew on me, and the immense customization became a tool from the vehicle to optimize a perfect driving experience. However, with all the great number of features and beautiful styling of the car I found it was easy to overlook the mechanics. One week after I purchased the vehicle, I noticed a "clicking" noise. Continued:
No regrets
I purchased the vehicle with 56,000 miles on it. I drive around 3,000 miles a month. I am 6'6" tall. The car is comfortable and rides great. It is a V6 and has enough power. I am partial to caddy's. My first car was a 1970 sedan deville. I should have purchased the all wheel drive for I live up north and the car is terrible in the snow. I currently have 114,000 miles on it with no problems. i change the oil every 3,000 miles. I am looking forward to reaching 200,000 miles.
Nice Car with a few defects
Purchase the car used with 38,000 miles. Engine consumes a quart of oil about every 3000 miles. Using the oil recommended by Cadillac which is Mobil One-5w30. No signs of oil leaks, no smoke out of the exhaust pipe. Cadillac drive OK if you don't mind the popping sound in the driver seat when turning corners. Also, sometime the lights in the dash below the speedo/tach go out. Our third Calillac, the last two had electrical problems. After 8 years with Cadillac, this will be our last one.
