At first i would have thought you were right but that was 4 months ago .Fact of the matter is NOTHING is moving .Car for car my ,mileage for mileage my car is thousands cheaper than any other 08 out there (low 60s is wholesale )and it still has not sold.ANY ONE out there looking to buy a VIPER is beating the HELL out of the sellers (new and used )untill the guy or dealer that needs the money the most gives in.
My comments are not meant to argue, but I've seen you struggling to sell. Take them as sincere.
Vipers are selling even in this market. A month ago I bought a 1200 mi. viper red/black stripe coupe for just slightly more than your asking price in the vca classifieds. I then sold my 7700 mi. 06 red/silver striped coupe for high 50''s in 4 days.
Your color is unpopular and a convertible is less desirable, especially in winter. I looked at autotrader and I don't see your car there? I did see a new green convertible for 69K and a number of vert's in the mid-60's and even 08 vipers at 59K. If you think mid-60's for your car is aggressive your not seeing the market. There's lots of new venon red's out there with dealers who are or will be in the 60's soon.
If you want to sell your viper I'd suggest you place an add in autotrader and price at 62K firm. And/or place a no-reserve auction on ebay with a starting price of high 50's. The market is soft but there are buyers, you need to price agressively and advertise agressively. Also, I'd skip the "price is right". I'll bet many folks think you own it for taxes only. Focus on 30% off, mint condition and lots of warrantee left. Also, let your sale posts die off, if someone wants info they'll send you a PM. Best wishes!
