Re: Converting 07 Marquis into Marauder
I think that the offset changed in '03 when they revised the suspension. Therefor you would need a spacer to put '03+ wheels onto an -'03.
The grill and header panel changed quite a bit in '06, so if you want a true Marauder look, you could either get the header-panel grill (maybe lights not sure) from a Marauder or an '03-'05 Grand Marquis. They are pretty much the same if you paint the marquis grill body-color.
The Marauder bumpers are different than the Marquis' bumpers so you'll want to get those too. Along with the unique Marauder exhaust tips, there are a couple companies that sell replicas. Megs, the company that made the originals, is supposedly going to make them again, available to the aftermarket. Of course Ebay has them occasionally.
1996 Mercury Grand Marquis GS ~89,000mi, Willow Green inside and out. It's very green.
1998 Chevrolet Malibu Base V6 187,000mi (sold)
