Bear in mind that the fraud charges leveraged against CMC specifically mentioned their fraudulent representation of the "required assembly time" and "quality of the kit car". That could well be the source of the builders "expectations".
From the court document PDF
It was the purpose and object of the scheme and artifice for defendant CMC to obtain money from customers throughout the United States for the purchase of vintage kit car replicas by causing employees under its supervision to knowingly and willfully make false and misleading statements, representations and promises and by causing such employees to knowingly and willfully conceal and omit material facts as to the quality of the kit car purchased, the delivery time to the customer and the required assembly time.
The Known issues with ALL kit cars
section of the Streetbeasts wiki article addresses the reality of building all kit cars, being sure not to point a finger only at Streetbeasts. It was Centerline who added that section, 2 days after I started the wiki article, and he was careful to point out that many of these issues are present in all kit cars, not just Streetbeasts.
MARTINSR makes a good point about the distinction between the terms "street rod", "kit car", and "replica". However, note the varied wording on Streetbeasts.com. They don't say "replica" -- they say "replicar" (in fact, they say "replicar" with a trademark symbol following it). They also make liberal use of the term "street rod". The terms are jumbled together and used interchangeably, such that they lose their distinct definitions.
Ease of construction and accuracy of appearance are minor side issues to me.
Streetbeasts's attack on our free speech, and their attempt to silence us with a frivolous lawsuit, is the most disgusting thing that any company has ever done to this website.
