The choice here in Aus is pretty good including:
DRB, Superformance, Classic Revival, Python, Robnell, Harrison etc etc.
First decision if you are serious is:
Buy or build:
If buy, like any car take someone along who knows about Cobra's - they may look the part, but if the builder has cut corners then you will have to spend the dosh to bring it up to scratch.
Personal experience says that a bloody looking car at $50,000 may still have problems underneath such as wiring, suspension etc. Remember it is pretty easy to get fanatical about these cars to a point that all your spare dosh ends up in the Cobra Pit
The other buy option is a turnkey car such as DRB, where they build it you drive it - cost is obviously dearer.
Price wise - second hand $30,000 to $85,000 - remember you get what you pay for.
Notwithstanding the above, follow the car mags for quite some time and you'll find a good Cobra that simply doesn't sell as there are not many buyers with that amount of dosh in their back pocket so giving you some bargaining power.
Build Option:
Not qualified to speak here, but will say that with all the rules and regulations you will run into serious issues if you stray away from the guidelines i.e. 427 forget it!
Although satisfaction of building such a beast is no doubt exciting, the cost of a decent build your own car must be in the region of $30 to $40K unless you cut out all the chrome!
I'm sure the builders will chirp in regards the cost.
I have a theory that whatever way you go, at the end of the day you should have a car that won't lose its value simply because its getting harder to privately build these things therefore lifting the second hand value.
How many times do you see a brand new BMW at $90,000 knocked down to $40,000 in two years. At least the Cobra (if built using recognised donor parts) will at least hold its value.
Good luck
