1. 1A GTC is defined by its build sheet — the color, stripe, wheels and interior a buyer specified. Get the original configuration documentation; a desirable spec is much of the value.
2. 2Confirm whether a car is a plain GTC or the 25-unit 2017 Snakeskin Edition GTC, which carries a distinct premium.
3. 3Run the VIN through nhtsa.gov. 2013–2014 cars carry three recalls: the frontal-airbag seat-position-sensor recall (14V529000, ~1,628 cars), the 'door may open while driving' moisture-in-switch recall (15V178000), and the 2013–2015 Uconnect radio cybersecurity software recall (15V461000). 2016 cars carry two more: pinched driver-airbag wiring (16V736000) and a passenger-airbag-chute weld that can let the airbag door detach (16V750000). Only 2017 is recall-free. Confirm every applicable remedy was performed.
4. 4Gen-5 blocks were prone to abrasive casting/machining debris left inside at assembly, which circulates in the oil and can destroy the rod and main bearings, sometimes at very low mileage. FCA covered about 1,100 2013–2014 cars under Customer Satisfaction Notification R28/R29 (engine oil contamination and consumption), a warranty campaign that will not show up in an NHTSA recall lookup; owners have also reported bearing failures on 2016–2017 cars. Get documented engine history, an oil analysis, and confirmation of whether R28/R29 was performed.
5. 5The clutch is the primary wear-and-cost item owners cite, especially on track-driven cars — aftermarket clutch kits are a common upgrade. Ask about clutch history.
6. 6Expect significant cabin and footwell heat from the V10 and side-sill exhaust routing. It is a long-standing Viper trait, not a defect.
