Review for LEGO set 2064 Air Ambulance from Brickset
“A great little set, if you can get your hands on it. Apparently, this set was produced for use as a promotional set by airlines, and as such wasn't readily available in retail stores. A limited amount was shipped out to two Australian retailers - K-Mart and Myer. Both... More retailers sold the set for AUD $19.99.”
