I can't see a problem, 4cy, v8, v12, diesel, electric...if it offers true performance it has my respect. Although I'm not sure about it in a Cobra.
Green doesn't necessarily mean you can't have fun.
Mind you RCR do electric versions of the Roadster, so I'm definitely biased.
But our replicas have remained faithful.
Mike, oh yeah, a Kirkham setup as a replica of a Super Snake...worth every cent.
