USA Kits - revival ?

[ugg10]

I have noticed there has been a number of (to my eyes) nice kits appearing over the last year or so in the US.

Ones I particularly like are -
Mx5 single donor, Lotus ThreeEleven stylish - http://bauerltd.com/
US answer to the Murtaya, scooby based - http://www.factoryfive.com/kits/project-818/
Single seater exo, VAG engine - http://superlitecars.com/index.php/cars/nemesis#17...

and an old one I have likes for a long time -
http://www.scarab-motorsports.com/

So, is the US starting to produce new designs rather than the plethora of replicas that has been the norm up until now, and how might these be made to be IVA compliant?
