I helped a friend a little with his build up of a factory five cobra. Being a donor car cobra its on the low end of quality and fit and finish. It in no way compares to another friends ERA cobra. Miles ahead in quality and money. Now this isnt a bad thing as long as you know this and have realistic expectations. Think all go - little show, i'd like one in primer black with a blown 351, but not at the expense of my 911.
Some of my impressions, the kit itself is pretty easy to complete, if you have basic car skills. Its basically a bolt on project. Majority of the parts quality is ok, Skip the powder coated frame its crap. Again a price point cobra so not much is top notch. Fiberglass Body needs quite a bit of prep work to look great. These observations are from a kit put together 2 summers ago so things might have changed.
Fast as hell and fun to drive, not much in suspension and cornering but it goes damn fast in a straight line.
