I just got mine the other day, and I must say, I'm impressed. Hot Wheels
did make it worth the high price. I'm especially glad that they gave it a nice shiny chrome finish and corrected the orientation of the no-ghost symbols so they weren't tilted too far. It's amazing the level of detail they even put into the engine; you can see the engine block and all the other little car parts in there.
For all the details Hot Wheels included, though, I'm surprised that they forgot to put in a rear-view mirror! I only noticed this because my 1:18 DeLorean time machine does have a rear-view mirror. And the funny thing about it in the DeLorean is that it's pointless in there when the entire rear window is blocked off by time-traveling equipment.
Now if only Mattel would give us a 1:1 scale proton pack replica, I could die happy!
