Probably will. On the bright side, the value will probably keep going up.
I plan to keep mine until I can't drive anymore so I don't think about resale value anyway.
In other news, the knock sensor went bad on my Slingshot. It actually runs better than when it works. Midrange power is up a bit and throttle response is much better. I think the ECU must run the mixture richer to avoid detonation since it can't hear it anymore. Down a couple of MPG though so I ordered a replacement. I'm thinking about installing a switch to disable it when I go to track days.
