I need a approx. value of my car for selling

[Hyper92GT]

The sad reality is you do not get anywhere near what you put in back. When I purchased my car the guy showed me the build sheet for the engine $10K!! (it was only a year old). That is basically what I go the car for.
So in the end you sell it for what someone wants to buy it for.
I think, after seeing your website (nice car BTW) that anything from $11k - $15k would be reasonable. It really depends on your local market. Here in T.O the prices of used 5.0's are going up because good ones are increasingly harder to find. Once you get into the $15k range though the car better be super mint and fast (ie for me a blower would be manditory at that price).

You have done a real nice job at restoration/improvement, now you need a buyer.
best of luck.
