Default Roush 427R, 428R, 429R...

In 50 words or less, what is the difference between the Roush 427R, 428R, and 429R? I'm doing my research on my next new car purchase (it's between the Roush, GT500 or Challenger SRT), and can't seem to find a whole lot of difference on paper between the Roush's.

427R is S3 powertrain, lacking in lots of body bling.
428R/429R limited runs using more bling.

How's that Jazzer?

Right on all counts except the suspension. All 427, 428, & 429s have a Modified Stage 2 Suspension. The modification comes in the front as changes were made in the springs and struts to accomodate the extra weight of the SC to keep the handling the way Roush wanted. Stage 3 suspension parts are all red. Stage 2 are all blue.

I own this car and have been told only 11 of the 100.. 429r cars were built as convertibles..any idea if this is correct? I have only seen one in the last year
