I don't think the recent dialog of what makes for a "good" Cobra is to far off the path as it considers the basic question, SPF or ERA, in this thread.

When shopping for a Cobra one would be well advised to consider those options that result in good overall street specification car. Regardless of make or model. Both SPF and ERA can come pretty close to what I would consider the "best" options for a mostly street driven car. OTHER criteria would have to be applied for a "show" car or a "race" car. SPF or ERA could easily fit any of the above catagories with different emphasis on the specs.

For "race", I would seriously consider an FFR based on price, performance, ease of maintanence and parts availability. But it would not be my first choice for primarily street use, for example.
