If they don't make a GTS, Vipers have probably seen their last endurance race - or Speedvision/Motorola cup race, for that matter. Oh, and probably a few less customers, too. Can't think of one true supercar that is NOT available in coupe form. My guess is Dodge has a better handle on what the Viper brand has evolved to than to produce only a convertible. Frankly, am a little surprised they're waiting as long as '05 (rumored around here) to produce a coupe.
