Hi Jack.
Welcome to the forum :thumb:
Firstly the Sebring is more a take off of the Healey, but still a good looking car
When you say that you want to be able to get all the right bits to finish the car, I guess you mean from the kit supplier, Which I also guess is why you favour GD. Dax also supply all the parts required. As do Pilgrim. I'm not sure if anyone else does, but i'm sure someone will put me right
AK supply the basics and leave you to source all the right bits yourself.
As with any kit car the end result is only as good as the time, effort and attention to detail imparted by the builder. So it really depends on you how the car ends up
There are stunning examples of all the marques, and some not so, regardless of the quality of the kit.
Exeter is the next show. Go along and have a look
Good Luck. Whatever you decide on :thumb:
