[steely]

I have seen Carrera tails range from $200 to $1200 depending on the condition of course, the rubber, the decklid, and the supporting tail material, etc.

I was keeping track for a couple of years and missed a couple of good buys due to bad timing on my part.
I bought a crummy one and was going to restore, but it was too shot, and the price of spraying the extra decklid that I had was too high.
I do not know what the Turbo tail would go for, but if you find one that matches your color, I would jump on it even if it had a dent or a blemish.
If you are new to this, double check to see if the tail for sale includes the lid. it isn't always the case.
