There seemed to be a lot of widely varying prices quoted on here for this. I was charged £1100 for the 2003 749s Asymetric system (with ECU) - fitted. I have no doubt someone will be along to tell me different, but that was waht I paid at Italia in Oct 2004. The implication was that I was getting a bit of a deal on that too.
That reminds me - must go and chase up that replacement ECU that was on back order!
Er yeah - ive been chasing this about for over 12 months and ive come to the conclusion that "the worth of a thing is measured by the want of a thing " and every Termi Ive chased on e bay has been wanted by about 50 other people. Ive seen second hand units going for over £700 and new ones for over £1000 ! They are quite hard to get second hand so let your mate know what a huge favour your doing him by selling it to him. The sound alone is worth every penny (as you already know.)
