selling on a scorpion 2nd hand i wouldnt imagine would get near as much percentage back of the buy price new compared to that of a nismo, the principle is like car buying, take a hyundai or a beemer, sure the hyundai offers a 7 year warranty, so surely they must be built to a good standard, but you would want the beemer....surely
if i had a zed, id personally be looking at an amuse, big dosh, but exceptional quality! titanium definately my favourite system
