After that, they produced the 2003 SRT-10 "Prototype" in red, black, and silver.
Next was the 2003 SRT-10 production version, also in red, black, and silver.
Then came 4 Competition Coupes:

Finally, their latest models, the 2006 SRT-10 coupes:
2006 Dodge Viper SRT-10 coupe black , white stripes LE (1/6000 )
2006 Dodge Viper SRT-10 red with white stripes LE (1/6000 )
There was also another Competition Coupe made, in very limited production. I believe one of the members here helped push it through:
2004 Dodge Viper Competition Coupe #28 Rudolph LE (1/100 )
I think that covers them all, but I could have missed some. Hope this helps!
