I know I've made some bad decisions recently, Dave, but I'm feeling much better
now..."
Our pals at Moebius sure know how to get our motors running. One of the rarest
and most popular of the Aurora model kits, the Moonbus from 2001: A Space
Odyssey was originally released in 1969 to coincide with the opening of the
film. This is a straight re-issue of that kit, including a litho-wrapped box
that reflects the original packaging.
The 1:55 scale kit includes a full interior with figures. The roof lifts off for
interior access like the original.
The suggested retail price is $49.95, but we're offering 10% off for pre-orders,
our price is just $44.95! This model will sell quickly and may only be
reproduced once - Pre-Order Now!

The Moonbus is expected to ship in Spring of 2010.
