Well
Don't you think they wouldn't have called it a DE for Delimited Edition..
Actually, all E34 M5's are not limited, but especially for the UK market ( read ; AndyE ) they came up with a 50-fold specially limited version (Rosso Red or Orinico) to prevent people from speeding on the M25
Would be nice though...It is an official option though,
top speed limiter remove..Saw it on a buildsheet once..Probably of a CSL
