I too just received the NOREV 1:43 XFR, but you say the top goes up and down on yours???!!!
On mine, the tonneau cover seems to be VERY solid and I don't want to scratch it or break it trying to open it up. The workmanship IS very good and I can't wait for a 1:18th version.
Check Ebay...I just bought a plastic RED XFR with a Blond behind the seat. "kidconnection #08423 and marketed by WAL-MART.
It isn't diecast but it's an addition to the mantle (up there with all the RED XFCs).
Those of you with Coupes...there are Black, White, Silver (SSB?), and Red Coupe Diecasts all over. I even saw a GREEN one??? 2006 Color???
Even though I don't have a SSB...I bought the Sharper Image CD/Radio SSB Crossfire.
But there are ONLY TWO XFR models out there... (to my knowledge).
