'96 Impala SS or '03-'04 Marauder?

I'm having a problem that maybe you can help me with. I need help deciding on which car to go with. The Marauder has more horsepower, is newer, and will probably have lower mileage, but the Impala SS has a much larger aftermarket scene. Which would you guys pick? Thanks.

(This is a repost, but I'm not getting much help in the other forum.)

Well Id take the Marauder just because its newer and being basically the same as the Crown Vic, you can get stuff for it that Police Interceptors have. Plus, its not exactly "attention grabbing" if your into that, but I've always favored it over any other Mercury just because its so subtle and "cool" IMO. But the Impala SS would still be cool, too. My coice is the MArauder when it comes to reliability and other mechanical issues, being newer there should be fewer than a 10 y/o Impala.
