For me, it would be CSX, ERA, and then Superformance.

In the world of fiberglass repliCobras, the CSX is alone at the top of the heap. Just look at the resale prices. No other glass car comes close. Mine has gone up in value quite a bit while I have owned it, despite the "experts" telling you that they are a bad investment. A rising tide floats all boats. The early ones are very close to an original. The later ones diverge a bit with suspension, electricals, gauges, etc.

I can spot a Superformance from a half mile away. The shape of the rear fenders and the grille opening/radiator are the giveaways for me. High quality, though, with many happy owners.

The ERAs are a little tougher to spot as their body and trim are pretty accurate. You have to pop the hood for a look to really be sure. Again, high quality, excellent support.

If you add in aluminum bodies, then Kirkham makes its entrance in the poll. But they don't make fiberglass Cobras, so that's not relevant to your question.

If I was buying again, I'd try to find a CSX glass 289 USRRC/FIA replica with a snotty small block and Webers. Just perfect.
