Im a cop and last night i was doing a road detail in my 2003 mercury marauder.
Then this older guy (about 70) in a MM drivng by stopped, and came over and started talking to me. He told me he had one of the six prototype marauders that they were showing in the 2001 car shows. he showed me the registration and sure enough it said 2001. He said he got it because he was friends with jack rousch, and jack sold it to him after it was done in the car shows. He said it the motor has 500 hp STOCK because of a big throttle body, injecters, etc. he said it had a 5 speed double overdrive transmission, 2.60 rear end gears. he said said it does the quarter mile in low 12's - high 11's at 137 miles per hour and he showed me the timeslips. he said he beats vipers and c6's all the time. I guess rousch went way overboard with the prototypes and that may be why MM's have such a bad-ass reputation. He is a retired mass state trooper so i believe what he says.
