There are several top notch kits out there and if you are buying turn key, see if there are any around near y that you can look at. You never said what make the one that you are looking at is, but ERA, Shelby, and Kirkham are some of the top line. And Factory Five is now right up there near the ERA level. Also if buying one already built a lot will depend on the way it was built. If the builder did a good job and used good parts, then many kits are good. Also look depending on what you are going to use it for. Are you looking for a cruiser,show car, or do you want one to race. Good luck with whatever you get and post some pictures of it.
