well it could be bad because if you paid $450 for the worldsport OR the N1 you pretty much just got ripped off, sorry to burst your bubbles, ive seen it cheaper at a lot of stores
especialy being used...
$450 is an ok price for n1 (new). it's decent although i still wouldnt classify it as a 'hook-up'
if it's the world sport..then it's way on the expensive side. i really can't say i've seen it for that high of a price anywhere online...although shipping can bump it up to that. definately not a 'hook-up' though..not even close.
find out if it's the n1 or world sport..if it's the world sport..return it, get your money back..or at least get a discount. and you can always order it from extremely reputable online shops for a lot less than that...install is a breeze, you can really do it yourself with NO trouble whatsoever. its basically 4 bolts & some hangers.
