first, we need to get on the same page:
1) GTS-R came out in 1995, GTS coupe based. Ran FIA, Lemans, ALMS, ROLEX, World Challenge, winning all but the last. All 'real' GTS-Rs were race cars, not street legal. A few have sold from time to time, now in collectors hands.
2) Dodge made a REPLICA, correct nomenclature GT-2, in White, with blue stripes only. Cosmetics only..... rare, desireable, 102 made, 98 for retail.
3) in 2000, the Auto-Show circuit revealed the GTSR/T coupe.
Called the "Concept Coupe" in these parts. This is probably the car you are romancing about. This show car spawned the Comp Coupe, a real race car. MSRP $100k. For sale (slowly) to racers and race teams.
(PartsRack offers) a body kit, made and installed by AutoForm, that they call the STREET COUPE that can make a 96-02 GTS look like a GTSR/T
