The Lego Ghostbusters Ecto-1 set has 508 bricks including four very cool minifigures of Peter Venkman, Ray Stantz, Egon Spengler and Winston Zeddemore. Sadly no Lego Slimmer was included. Each minifigure have their own proton pack and accessories.
The Ecto-1 is very cool. Lots of small details and accessories. It was a fun vehicle to built (something I can't say about… the Lego TMNT truck).
It also comes with a very nice perfect bind booklet. Overall a must own Lego set!
