That car's very fixable. Use the new space-age Bondo-like goop on the hood and the bumper cover, throw in a used radiator and condensor (unless you wanna delete the A/C), buy some airbags from another wreck, and you're back in business. Cheap ****** GTS will result...one to drive the hell out of and not care about resale value or gravel dings.
Viper wrecks have become more expensive in the past three years...a couple of summers ago, even Gen I high-mileage cars were getting mid-20s on online insurance auctions open only to dealers and salvage rebuilders. I know a rebuilder who's done four Vipers, and he stopped buying the wrecks when they became too expensive to fix at a cost-effective price. Hobbyists may not care about that, as most won't dump all the $ into the car at once. A hobbyist might spend 50 - 60K fixing that car (including purchase price), but it'll be done over a number of years to lessen the financial impact. Just look at the backyard musclecar restorers and you'll understand.
I'd buy this car after it's fixed, but I'd pay no more than $25K, and only if it's fixed right, mechanically. Who cares about paint...any decent painter can fix rebuilder boo boos.
Having said all that, this car could easily bring $25K the way it is.
