I would be very hesitant to buy a highly modified car, such as an S/C, that has not been down the 1/4 at least 6 times.
The 1/4 is controlled and documented that the car gets to go WOT for ~12 seconds.
Get one of these - you will get more attention and it will never allow you to abuse your Marauder;
