CTS-V wasnt even around when my S4 was out, and like jones said, no AWD.
As for being a big POS, well that's your opinion. The earlier models were great, if not the best, for doing what they were designed to do. No they weren't the most reliable things ever, but were capable of a lot more than most others. Now for the LR3's and newer range rover's they are built a shit ton better, even better at off roading and a shit ton nicer. You're also basing your opinion off of hear say.
Anything that's an SUV with 4WD is in competition with Land Rover (mostly), but LR stands out for a reason. I don't buy shit just to buy shit, there is a reason for it. A car is a machine/tool and I want what I think is the best for what I'm looking for, at a price I can afford of course. Also in my family we've had almost every type of car from every country that makes cars (benefit of growing up in another country), so I take from experience as well. From Alfa, to Dodge, Ford, Opel, Mitsu, LR, Mercedes, BMW, Toyota, Cadillac, Renault...and out of all of those the American ones are the ones I dislike the most.
