Quite, i'm just not of the opinion that eBay is the right course for a horse like a nice 350z asking for good money
Like others have said it's the wrong time of year to sell it. You'll have better luck selling it March/April time.
Don't see the problem listing it on ebay. It gets you out to the biggest audience possible, and anyone who is seriously interested in the car will view it and possibly negotiate on viewing it anyway, just like they would with Autotrader / Pistonheads, so I don't see the issue.
