The dictionary defines "marauder" as a person or animal that roams from place to place looking for opportunities to attack, raid, or destroy. While The Big Three love alliteration to name their vehicles, "marauder" is still a rather curious moniker to use on a vehicle. The Ford Motor Company's late and most often not so great Mercury division named three supposedly high-performance, full-size cars such; from 1963 to 1965, 1969 and 1970 and in 2003 and 2004 when they gussied a Grand Marquis into the scariest grocery getter this side of the time I affixed an old lawn mower engine to a shopping cart. This 2004 found me on Facebook Marketplace for sale in the town just west of us here on the far west side of Cleveland, Ohio.
Mercury sold just 11,052 of these cars combined in 2003 and 2004; 3,204 in 2004. Therefore, finding one these days is rare. Asking price is $10,000.
Such a deal, right? Before you go running to the ATM, buyer beware. Apparently, the seller didn't heed the warning signs before buying it and now, it seems, they're trying to recoup their losses.
Founded in 1938 as a mid-priced brand intended to bridge the price gap between Ford and Lincoln, Mercury spent much of its existence occupying an awkward spot in the Ford Motor Company hierarchy. Save for a smattering of models, such as the 1967–1970 Cougar, a Mercury was generally either a dressed-up Ford or a scaled-down Lincoln. The Cougar itself a dolled Mustang but they get a hall pass because they did such a nice job. Being sold primarily through Lincoln-Mercury dealers didn't exactly help establish Mercury as a brand with an identity of its own, either.
If anything, these cars most likely confused buyers. By the early to mid '00's, Mercury's image was so "old", this car was akin to hot-rodding the little bus that takes oldsters from the assisted living residence to the mall and back. Frankly, if they felt compelled to do something like this, had the Ford Motor Company simply hopped-up a Ford Crown Victoria with the same go-fast baubles and bits, it would have sold better. I'm sure there were 1994-1996 Chevrolet Impala SS fans who would have signed on the dotted line for a Crown Vic "SS".
Sharing the Panther platform with the Ford Crown Victoria and Lincoln Town Car, Marauders got a number of heavy-duty chassis components and suspension upgrades, along with the 4.6-liter DOHC, 32-valve V-8 related to the engines used in the Mustang Mach 1 and Lincoln Aviator.
Stripped of much of the Grand Marquis' usual brightwork and dolled up with a monochromatic, blacked-out treatment, the Marauder also received plenty of chassis hardware to go with its sinister appearance. The suspension was considerably firmer than that of a standard Grand Marquis, with unique front springs, Tokico monotube shocks and a larger front anti-roll bar. In back, the car used load-leveling air springs, while the 2003 revision of the Panther platform brought rack-and-pinion steering and other chassis improvements.
The rims are 18-inchers shod with appropriately meaty tires, and they're staggered, the Marauder wearing 235/50R18 tires up front and 245/55R18s in back.
The rear axle ratio was also bumped from the Grand Marquis' typical 2.73 or 3.27 gearing to a 3.55:1 setup with a standard limited-slip differential.
If these cars had an Achilles' bumper, it was under the hood.
Despite Roush Performance's involvement in developing the intake manifold and dual-exhaust system, the big 4.6-liter DOHC V-8 made 302 horsepower and 318 lb-ft of torque. That's respectable, but moving a roughly 4,200-pound barge with a four-speed automatic transmission isn't exactly a recipe for tire-smoking acceleration.
Contemporary road tests put zero-to-60 mph at roughly 7.5 seconds, while the quarter mile came in around 15.5 seconds at roughly 91 mph. Good, but hardly remarkable.
Fuel economy wasn't exactly the Marauder's strong suit, either. EPA ratings were only 15 mpg city and 21 mpg highway, and the 10.1:1 compression ratio meant Ford specified 91-octane premium unleaded for optimum performance.
An attempt to fix the lack of real go-power on this car was apparently made by the person from whom the current owner bought it.
An Eaton M112 supercharger was added, along with an Aeromotive 340 fuel pump, heat exchanger, intercooler, high-pressure fuel injectors and various other baubles and bits, all in the interest of literally boosting horsepower and torque.
There are no raw numbers indicating what those mod expensive moifications did to the engine; I'd figure 60- to 75-horsepower, but there's a caveat: Although the person who posted the ad claims the car passed local emissions testing when they first bought it, something has apparently gone kablooey with the engine tune since. Not only will this thing no longer pass a local e-check, but it's not even running.
Exhibit A, your honor, as to why you should never buy cars that were modified. Good luck finding a mechanic who'd even look at this thing.
They can provide video of it running, though.
