The most accurate is John Watson -aka air dynamics
His kit is separate pieces molded off a real car so it's closest to the real thing
Plus the quality of his fiberglass is great
But because its exact copy there is no donor chassis you have to
Build a custom chassis or modify a car a lot
The g28 is the most popular body as its cheap and made to fit a fiero with a stretch . Carkitinc and robslp640 are the most popular sellers but both have plenty of negative comments from purchasers about quality
There's a guy in Michigan I believe his website is lambo replica forsale.com that started making some nice looking bodies but few buyers to comment on quality yet
