Several years ago, in the height of the factory-sponsored Viper racing seasons, Dodge put out a great poster with a picture of a GTS-R in front of a yellow Corvette C5R. The caption said "Hisssstory Lesson. Viper: 12 wins, Corvette: 0." Text: "Over the last two years, race-modified Vipers have won two victories at Le Mans. The first American-based production car victory ever at the 24 hours of Daytona. Every American LeMans series race we entered, including a 1-2-3 finish at Sebring. For a total of 12 wins in all. Which, by the way, is 12 more than Corvette."
(After that poster was published, the Viper streak ran to 14, before Corvette finally won an ALMS race.)
Other accomplishments listed on that poster:
<UL TYPE=SQUARE>
<LI>1st place, 12 hrs of Sebring, 1997.
<LI>1st & 2nd, 1998 24 hours of Le Mans
<LI>1st, 2nd, 3rd, 4th, 5th, 6th, 1999 24 Hours of Le Mans
<LI>1999 ALMS Drivers Championship
<LI>1st, 2nd & 5th, 2000 24 Hours of Le Mans
<LI>1997, 1998, 1998 FIA GT Drivers and Manufacturers Championships

Add to that the 2000 ALMS Manufacturers Championship (I think).
The "Hisssstory Lesson" poster may still be available from Viper HQ.
