I really like my 2003 300A Marauder. I've owned it for about 2.5 years and I love it as much as the day I bought it. You can find out just about anything you want about them at MercuryMarauder.net
I traded in a 1993 Lincoln Town Car on mine and it had 230k miles on it. I hope to get more than that out of my Marauder. It has 90K on it now. Be advised, there is a problem with early 03 Marauders, Crown Vics and Marquis'. The rear axle bearings tend to go out. There is a Technical Service Bulliten for this and a kit to upgrade it to fix the problem. Get yourself a Marauder and you will find out what all the fuss is about. Mine is still stock and it is still the best ride I have ever owned. Many Marauder owners get 4.10 gears, a super charger and a tune and go to the drag strip! These cars are great!
