Shell Valley and NAF are budget kits. Their quality will depend VERY heavily on the fabrication skills of the individual who assembled them.

Unique is in an entirely different class. They've been building these things longer than almost anyone else, and remain a family run company with outstanding customer service.
Unique's car is well engineered and first rate throughout.

There are several top notch manufacturers out there, ie: ERA, Unique, Superformance, Kirkham, and others.

Do your homework before jumping into the first thing you see.
