Tavas, my advice would be to have a good think about what you want out of your Cobra. I expect you have already been doing that.
But it does help to put down in writing exactly what you want.
First make a list of the mandatory aspects you require in your Cobra.
Next make a list of optional items you would like to have.
Then research what kit brands will support all of your mandatory requirements and has support for the largest number of optional items or can be modified/upgraded to support your requirements.
Not every kit brand will be able to support all requirements, this is where you will need to do some research.
Some aspects you might consider:
* Fitment Issues - what height/size driver needs to be supported, do you have multiple drivers of different sizes and thus need seat sliders, does any of the drivers/passengers need comfortable sprung seats etc.
* Safety Issues - what safety requirements do you want - structural rollbar for drivers and/or passenger.
* Engine Type/Size, HP etc.
* Wheel Type/Size - Pin Drive or Bolt On, Deep Dish, how wide wheels/tyres
* Body Shape - what body shape pleases you, are you concerned about how accurate the body shape is not really worried.
* Side Pipes - do you want functional side pipes?
* Performance - is performance/handling crucial or do you just want a weekend cruiser?
* Racing - do you want to do any racing, if so what type and how often/competitive?
* Budget
* Etc
If you post your requirements the generous people on here can suggest the best kit brands and even if it will be financially viable to buy used and get what you want for the budget you have in mind.
If you shop wisely you could get something that you can enjoy now and enhance over time to be the perfect vehicle for you over time. Or it may mean that the only way to get want you want is to build or your available funds may mean you need to spend money required over an extended time period.
We do this for a business and have customers where a new kit is not suitable, so will advise and match owners with the best matched used Cobra kits for their requirements and perform any restoration/modification work they require.
Great start by jumping on here and asking questions. And if you haven't, join your local Cobra Club and get down to meetings and see as many Cobras as possible and chat with owners. You don't need to own a Cobra to be a member, you just need to be a Cobra enthusiast.
Good luck with it.
