97-00 FICHT 150/175's are a crap shoot at best, and almost like playing RUSSIAN ROULLETTE. I heard there were ALOT of upgrades for them and if not performed they can be rather troublesome. The EMM's are the biggest problem from what I have heard and read, and are about a once a year repair job to the tune of $750-$1100 every time. The early FICHT's used an air cooled module that failed frequently. Make sure it has ALL updates, and I would check to see if the EMM's have been updated by DFI TECHNOLIGIES. If not RUN away.
