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 an unlimited build with stage3 suspension for '07 thru '09.
428R is a limited build of 200 cars for each model years '07 & '08 with stage3 susp. and polished supercharger.
429R is a limited build of 100 cars for '09 only with polished S/C and stage3 susp.
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.
In previous years, all Stage 2, 427R, Blackjacks, etc had the blue stage 2 suspension parts. Only the Stage 3 cars came with red suspension. The reason behind this was that the calibration was different due to the lighter forged wheels on the Stage 3. All the other Roush cars came with cast aluminum wheels.
If your brakes are red, then you must have the Roush/Stoptech big-brakes.
What is bling? Bling is typically really nice or shiny autoparts. Think of it as automotive jewelery.
