Yeah the boom is slowing, not everyone has the money that did or had hoped for.
This car on the other hand, no idea whose it is/was, but I rekon a touch on the higher side price wise, but still decent, especially with what I would consider slightly below average km's.
And who writes power figures like 330hpawd? pretty sure its whp/atw or whp - so maybe he hasn't done the work? either way ask for proof of the 330whp.
motec? also check that out. every thing else on the mod list is pretty std & have a good squiz at how the fmi is plumbed. judging by his add he doesn't really know what he has, prob paid too much for it, and if his reasons to sell it are genuine, you may have room to bargin.
