It is nothing like a Crown Vic or Grand Marquis. The list of differences is bigger than the list of similarities. Other than the body panels, that's about where it ends. To say it's just a blacked out cop car is ignorant. It's like saying an STi is just an Impreza with BBS wheels.
A Marauder is not a cheap car. For $35k you could easily own a Corvette. You won't be putting 5 people and their luggage in it though.
You must live in a world where every car is stock. In that line of thought, 14.0 for a WRX ain't all that fast; certainly not that much quicker than a Marauder to make fun of them. Negating an AWD launch, a Marauder is just as quick as a WRX from a roll, both trapping around 95 mph. Compare it to an automatic WRX and it gets even closer.
There are sleeper plain-Jane Crown Vics that'll leave you wondering what happened (for example, how's 12.50 @ 110 on 93 octane & plain Dunlops?) An understated car is much more enjoyable than one that yells to the world "Hey, look how fast I am!" Look at a black debadged WRX to see what I mean.
There are many 400+ rwhp Marauders out there. It's no slower than a stock Impala SS, yet I don't see anyone bashing them. Give the Marauder platform 10 years to be developed and they'll be just as fast and even more rare.
Laugh all you want at the Marauder board's reactions. I'm sure the same thing would happen over here if someone registered the name RWDV8OWNZU just to post about how easily he blasted WRXs. I've plastered just about every make & model out there and I don't join their message board just to let them know about it.
