Dodge Viper (fourth generation, ZB II) buying guide

The fourth-generation Viper punishes a car with gaps in its history: some owners report overheating, and others have had the rear differential fail at around 40,000 miles.

The ZB II ran from 2008 to 2010 as a Coupe and a Convertible (the Roadster), with an 8.4-liter V10 making 600 hp and 560 lb-ft, and a manual gearbox only. There was no 2007 model. The 2006 car carried on through that year while the factory retooled for this heavily updated one. It suits a driver who wants a manual-only car with no electronic safety net and will take care in the wet.

Stability and traction control are absent, as Exotic Car Hacks and The Cobra Magazine both note, and Kelley Blue Book confirms there is no automatic option. AutoTrader.ca calls the powertrain primitive but says it has made a largely reliable car, with fussy doors and windows.

• Have a Viper-trained technician in a dealer setting inspect the car, which Driving.ca advises and AutoTrader.ca says typically costs $200 or less.
• Check the cooling system for coolant condition, hoses, the water pump area, thermostat, fans and radiator, and look for oil and coolant cross-contamination.
• On the test drive the temperature needle should settle around mid-gauge, and the heater should blow plenty of hot air.
• Listen for scraping or grinding as the clutch is released, which can point to a worn throw-out bearing.
• Rear differential binding, whining or heavy clunks are bad signs, and the seller should say which gear oil and friction modifier it holds.
• Look under the car for leaks from the transmission, differential and engine, especially at the front timing cover.
• Make sure the car has not been crashed, and ask the seller directly about its history.
• Rocker panels and exhaust covers need a look for paint damage and rust, since they are expensive to replace.
• Work every window and door, watching for sag and water leaks at the seals.
• On a Convertible, inspect the top and its seals for wear and leaks, and look for leather that is dry and crispy.
• Ask for records of fluid changes in the differential and transmission, with proof that only factory-prescribed fluids went in.

NHTSA's records show no recall campaigns for 2008 to 2010 Vipers as of October 31, 2026. One source lists airbag inflator recalls as applying to these years, so run any car's VIN through NHTSA's recall lookup before you buy.

Owners have filed 3 complaints with NHTSA, one each about the electrical system, engine and engine cooling, and suspension. Two involved crashes and one a fire. They are reports, not proven faults.

Buy a 2008 to 2010 car whose owner can show differential and transmission fluid changes with the factory-prescribed products, and whose cooling system passes a specialist's inspection. CarBuzz calls third and fourth-generation Viper models performance bargains, and you can see what is listed in our used Viper listings and the Viper price guide. Our used Dodge listings and the best used sports cars list offer a wider view.

Skip a car with overheating the seller cannot trace to a cause, since the range runs from an air bubble to a failing head gasket, and skip one that whines or clunks at the rear. Choose the ACR only if you will use it on a track. The car has no stability control, so it asks a lot of its driver in the rain.
