2006 Cadillac DTS Performance 4dr Sedan (4.6L 8cyl 4A)
I had one of the first Northstar engines in 1993 on a Cadillac Eldorado. I was very happy with that engine so I had to get the Performance model in my 2006 DTS. It took me a short while to learn about all the toys such as heated/cooled seats and the massage feature. The Performance model has all the toys but is well worth the purchase just to get the engine. After I sold my 1993 Cadillac I went in 2000 I went with a Lincoln Towncar Cartier Edition. The car was fine but I missed my Cadillac. The DTS rides and drives great and the Performance model is the one to buy. Get the added chrome wheels. It really sets the car off. I am very happy.
The performance model engine, smooth ride, OnStar and phone built in, heated/cooled seats and the heated steering wheel. Get the chrome wheels.
It gets about the same gas mileage as my old 2000 Lincoln. I know the engine's bigger but 6 years of engineering should improve miles per gallon.
