I believe you have asked two seperate and distinct questions.
Question # 1 - "quite a few on the market" - There was a time back when that there was no Cobra reproductions, just originals. At first when they were first reproduced a market void was filled and the numbers were still low. Today there is what, some 50 or so companys that make them. Some large companys, some small. Along with the higher production numbers the cost to replicate them has been driven down too. This has in turn opened the market to a larger group of middle income folks and that in turn has driven further sales.
I saw the same thing happen in the rod market to 32/33/34 Fords, when the the steel car supply dried up. Today there is no shortage of rod manufacturing companys.
Now with a Cobra, in most cases I'd bet most of these reproduced cars are still around. Indeed- seeing a Cobra today is not a rare sight anymore. So 1/2 of the answer is they are still making them. And there is already a bunch of them.
Second question - Why are they selling them? I will answer that with a question. Do you still own the first car that you ever bought? Redundant question? I think not, as people sell cars for as many reasons as there are cars and people in the first place. And since most of us don't "collect" cars I suspect that most of us has sold or will sell every car that we have or will ever own.
A better question may be- how long have you owned your Cobra or a cobra actively. Sounds like it might be a good thread on CC.
