i find it hard to believe the srt-6 will appreciate. its just an slk 32, not that unique. if it does, more power to you, but i really doubt it. if the car isn't desirable now it probably won't ever be, except for maybe us here. it is a great buy though. i personally think it should be a collectors piece, but the majority of the public and press didn't take to the looks the way we did.
