I agree about the luxury/SUV B/S.
The two DONT mix!
The last real Cadillac was the 1996 Fleetwood Brougham.
This car is/was a real beauty and very advanced. This body on frame, rear-wheel drive V8 sedan had a 350cu" (5.7) that put out 260 HP and got 27mpg.
I test drove one of these. It was very quiet and powerful. One of the most luxurious cars I've ever 'piloted'!
It's a shame that GM discontinued this model.
