How much is a 1999 Viper worth?
Prices for a 1999 Dodge Viper generally range from about $70,000 to $150,000, with condition and variant driving the spread; GTS coupes tend to fetch higher than the roadster RT/10, and exceptionally low-mileage examples can command more.
Variant landscape in 1999
In 1999, the Dodge Viper lineup consisted mainly of two Gen II variants: the hardtop GTS coupe and the roadster RT/10. Both used the same 8.0-liter V10, but the GTS’s closed cabin and limited production numbers tend to push its value higher in the market when compared to the RT/10 roadster, which remains highly sought after as an icon of the era.
Typical price ranges by variant
Prices vary widely, but typical ranges observed on major marketplaces and auctions as of 2025 are:
- 1999 Viper RT/10 (roadster): commonly seen in the roughly $85,000–$150,000 range, with very clean, low-mile examples sometimes reaching higher figures.
- 1999 Viper GTS (coupe): commonly seen in the roughly $70,000–$120,000 range; exceptional low-mile cars can push into the $130,000–$180,000 territory for top-condition examples.
Concluding: The GTS generally sits at the lower end of the spread for variability, while RT/10s—being rarer—often demand a premium, with price swings driven by mileage and provenance.
What drives the price
Several factors determine the value of a 1999 Viper beyond mere variant:
- Condition and cosmetic/Mechanical cleanliness: showroom-quality or meticulously maintained cars command premiums; driver-grade cars are cheaper.
- Mileage: lower miles typically raise value, especially on well-kept examples.
- Originality and documentation: matching numbers, original parts, comprehensive service history, and verified maintenance raise authenticity and value.
- Modifications: tasteful performance or appearance mods can help or hurt value depending on buyer preferences and whether parts are revertible to stock.
- Color and rarity: rare color combinations or factory options can add value, while more common hues may not.
- Market timing and location: regional demand and auction timing (BaT or classic venues) can affect price.
Concluding: Expect the best prices for low-mileage, original, well-documented cars; modifications and provenance will heavily influence how high or low a price lands.
