selling cars on an enthusiest site will be hard unless its something rare and sought after. alot has to do with timing too.Yeah realistically I would say between $16k-$17k unfortunately. That being said I would put it up (autotrader, cars.com etc) for around $20k and see if some idiot bites. It seems that selling a car on Swedespeed (or any enthusiast forum) is particularly tough because people know the in's and out's of the car (exactly what it "should" be worth) and always seem to want to nickle and dime you. I would think you might be better off using another site but its always worth a try to throw up an ad here on SS.
Thats an awesome post with lots of great data! +1 to you! I think the s60r market is saturated yet the is still a decent demand for v70r'sSpeaking from the retailer standpoint, R's right now in any market are a hard sell unless you've got someone that's really hot for it. Going by the marketing data, there's about 39 2006 R's being listed online for sale, with an average asking price of $15,668, and a 75 day market day supply. The scary thing is that wholesale value on the car is right now higher than market average asking price. Looking at recent sales, most of the ones that have sold have been in the 14-17 range, though you do have the one odd one up in Portland, OR that sold for around 20. If you price it at 18k, that's going to put you in the highest 10% of prices in the country for that car.
If you're going to try to maximize value, especially in a market like an Autotrader or Cars.com, take lots of photos (30+), make a killer description with the main features at the beginning, and shoot some video to throw up on youtube and other video sharing sites. That's the best way to go.
