Hi IK
Can I make a couple of suggestions , from someone who has sold 6 cars this year now , and 4 of which I sold via ebay at a fixed price listing it's 30 days and only costs £14.99, so represents great value. Someone for Germany bought my Audi last month as it represented good value so was worth the trip.
The reason I used ebay now is that it reaches a far great audience, than pistonheads which is limited at best and that’s before they made everyone pay for an ad (I used to use it loads). Also the forum is quite niche as well so many not reach a big enough audience and Autotrader is far too expensive for a decent ad.
Of course this is IMO but just based on my experience I would suggest its worth ago, most mortgage offers are valid for 6 months so you should have a bit of time on your hands.
On a separate points I would also take new pictures of the car, it looks stunning as she is but you’re selling a product so therefore a pictures is a thousand words you want a scene that focus on the car purely is only best advice. I normally nip up to a big house and gates which is national trust I think up near Malmesbury , as it’s a stunning setting and would match a beautiful car like yours.
I think the write up is great very informative , the only thing I would knock out of the ad is the reason for sale , as it puts you at a disadvantage as they know your circumstances I would purely put genuine reason of sale. Also if you do place the car on Ebay put her up for £12999.00 with best offers give yourself so room for movement as people like to feel there getting a deal.
This was my last ad on fleebay - http://www.ebay.co.uk/itm/290620633742?ru=http%3A%2F%2Fwww.ebay.co.uk%3A80%2Fsch%2Fi.html%3F_from%3DR40%26_trksid%3Dm570.l1313%26_nkw%3D290620633742%26_sacat%3DSee-All-Categories%26_fvi%3D1&_rdc=1
This is of course only my view and I could be talking rubbish!! and please do not take any offence only trying to help a fellow member, but I have personally sold 50+ cars and every time I have sold within 3 weeks for a price I wanted. The Pictures are so important as is a professional write up as most people are happy to travel these days.
Best of luck with the sale
P.s if you use ebay when doing your listing go into hmtl section and input your pictures via this that way the appear in the ad and no cost to you!!
