Most seasoned car enthusiasts will agree on two things: modifications can make a car much more entertaining to drive, and they can also significantly impact the future value of said vehicle. This 1999 Dodge Viper sports a variety of custom tweaks that the owner likely thinks makes it a superior vehicle compared to the way it rolled off the assembly line, but future buyers may beg to differ. This particular Viper not only comes with an aggressive front and rear spoiler kit and blacked-out headlights, but also numerous performance upgrades. Find it here on craigslist for $70,000.

Now, listen: to each their own, and live and let live. Those are important epitaphs to remember when looking at a car that has clearly been personalized. The trouble is the seller doesn’t tell us much about the aero enhancements, and I genuinely wonder if they have some purpose beyond purely cosmetic. The Viper is often used as a track car despite its straight line speed, and the aggressive front air dam, rear wing, and rear apron diffuser could actually be purposeful upgrades. The seller doesn’t confirm, however, that this Viper was a track day build, and the blacked out taillights seem to suggest otherwise. It’s nice to see the factory roof panel in place, however.

The seller reports that they’ve spent upwards of $35,000 on this Viper in the time that they’ve owned it. This purportedly includes a new timing chain, and all engine gaskets. Upgrades included in that number range from Belanger Headers to a Billy Boat BBE X-pipe exhaust to ported and polished heads. Inside, you’ll notice in other photos that the bucket seats appear to sport custom leather upholstery, but the cabin otherwise looks largely stock. The cockpit of a Viper is fairly crude in construction, so gaps and chintzy switchgear came standard. With over 90,000 miles on the clock, it still looks fairly decent.

And while that V10 is known to be one of the cheaper “exotic” drivetrains to maintain, closing in on 100,000 miles on any car is a time in which owners either double down on maintenance or cut a vehicle loose. The seller of this Viper seemingly is just in the mood for something different, and if you don’t like his choice in mods, fear not – he has retained all stock parts. If it were my car, I would remove the spoilers, front bumper, and head and taillight covers before listing it for sale. The impression of the car would be significantly better, and you could still recoup some of the money on the aftermarket parts. Would you pay the asking price here, even if you didn’t love the mods?
