I don't know about the svt on 494, but the silver frost at Curtney Truck getting the work done was probably mine....and I am actually planning on selling my svt w/in a month or so (no problems - its been a fantastic car so far...I just made the mistake of test driving an S4). Let me know if you are intersted in a nicely modified svt, but it has the sunroof. There are a couple of guys on here who have svts and live in the Plymouth area, I bet you saw one of them. Good luck on your search!
