That is a good question. I really have no idea since many are not really on the market with mileage on them. I would probably say High 70's low 80's.
F355, with as much respect to you as possible and I apologize ahead of time for the many ways my response will be misunderstood or construed by you and others; and yes the question was asked and an answer is appropriate in coming. In my humble opinion, you have single handedly undermined the value of the SRT-10 and SRT-C more than any one single factor in the market by your constant "expert" responses to the values and score keeping you have done on Gen III pricing.
I really am sorry sir, but with all the banter, debates, posturing and foul play I and others have done on this forum, I have never disliked a person's opinion more than yours with your constant responses to the Gen III value and styling expertise. Water will seek it's own level and your constant devaluing the price will have a lasting affect. Possibly you could have waited for one of the dealers that frequent this board and there are a few, before you answered in your normal one or two sentence post number building. Is it necessary for you to comment on every post and every response with the "hmm, sounds interesting" or "me too, I like the color" post number building style you have so expertly crafted?
Again sir, I really do apologize to you for being so offended by your responses on value, its just you seem not to be able to help yourself. Please be assured, the value of my car is what it is, but there are many you have hurt. And yes, because you are a constant poster on this issue, all it takes is one person like yourself to do so much damage. Consider when a newbie or interested possible buyer reads such off the cuff responses by a person of your stature in regards to the VCA Forum, do you really think you are doing what is best for VCA, the Viper and its future if there is one? How about the guys that paid MSRP because they had to have the car right now and later venture in to this forum. I truely believe it is not your intention to do harm and you are probably a very nice young man but if you would please stop being the formost expert on Gen III values it would only add to your stature in my opinion, of which I may be a minority of one.
I am really going to catch hell for this, so flame away if you must. I probably deserve it just for letting you get to me, sorry.
