[REAL 1]

I don't think the manual is a big issue with the CSX as the vast majority of CSXs are fitted out by dealers to completion. A manual would be helpful though regardless.

I also believe that the vast majority of owners of glass CSX Cobras are very happy with the quality of their cars.

While both ERA and SPF are great cars and excellent products I can't think of a reason to justify buying either of them over a Shelby for the prices noted above. There would have to something very specific about the ERA and SPF that I really valued or wanted to make me opt for them over the Shelby at those prices. At those prices there are just too many reasons making the Shelby the best buy, quality being comparable on all three.
