This is actually one that is a little frustrating too:
Dodge Site:
Ram SRT10 Regular Cab
MSRP starting at $46,625**
Ram SRT10 Quad Cab®
MSRP starting at $51,710**
Viper SRT10 Roadster
MSRP starting at $85,745**
(note, it is not a roadster, it is a convertible, roadsters tops are completely removable, like the 92-02 RT/10 Vipers)
SRT10 Coupe
Base MSRP : $86,995
I'll have to dig through my older order sheets.... but I thought it was just the "Viper SRT-10" on the older order sheets, no designation past that. Bill Pemberton: If you ordered an Viper SRT-10 last year, did it designate past the "Viper" name?
Off the top of my head, I'll fill out a little of John's list:
RT/10:
92-95 - side exhaust, side curtains, mfg. and Mack Avenue
("Last 300 Side Exhaust" cars in '95)
96- rear exhaust, side curtains, first model mfg at Conner Ave. Assy. Plant (CAAP)
97-02 - rear exhaust, roll-up windows
GTS:
Base 96-02
ACR
R (racing - early cars made at CAAP, later cars made by Oreca)
GT-2 (sometimes incorretly called a "GTS-R")
Final Edition
SRT-10 03-current (Side Exhaust Convertible)
Base
Mamba ('04-'05)
VCA Edition-yellow ('05)
Copperhead ('05)
Commemorative Edition ('05) - white/blue stripes (thanks Paul)
Viper Competition Coupe (Side Exhaust Coupe)
SRT-10 Coupe 06-future (Side Exhaust, Coupe)
Base
First Edition
This ignores the one RT/10 ACR VCA Raffle Car.
