You'll find this out eventually, but an SRT with the electric rear spoiler does not exist unless it has been modified. All SRT's come with a fixed rear spoiler from the factory.

As far as supercharger reliability, you should be fine. There are several people on here with SRTs and I can't recall anyone losing a S/C. Not that it can't happen, but it would be rare. Several owners "think" the S/C starts to fail but in the end, it turns out to be the IC pump which is a fairly easy and inexpensive fix.

In my opinion, owners that are not members of this forum will unload their SRTs for lower than average sales prices because they believe their S/C has failed and the dealers don't have a clue that it's a simple fix. I think that's why mine was so low priced (less than 10K).

Good luck on your searching!!
