As a collectible, I assume there's some value if you keep the mileage low. If I was in the market, $17.5k doesn't sound unreasonable to me.
The carfax says he's owned it since 2007 and it came with 5,700 miles, so he hasn't driven it that much. The mods and warranty alone are worth at least $2k. I'm suprised he didn't have photos of the engine in his ad. I guess it depends on car's condition and your preference.
