I'm strongly considering getting this facelift for my Signature Model S. I wrote to the company with three questions:
1. Is the modification reversible? (e.g. if I sell the car and the buyer prefers the original look, or if the new face gets scraped up in a fender bender)
2. The earliest S'es had a slightly different nosecone than later ones; does this affect the compatibility of the new facelift?
3. Can they do it in Signature Red?
Also (just occurred to me), how does this modification affect access to the tow hook, which I believe is under the original nosecone? (Or the 12v jumpstart connections, though that's less critical.) I'll post if/when I hear back the answers!
