Our latest featured LEGO set is the City Ambulance 4431 first released in 2011. The set is made of 199 pieces. It was designed for ages 5 to 12. There are three minifigures, two paramedics and a patient. The stretcher is one of the more detailed versions. It includes wheels and an IV stand. The paramedic also holds a big scary syringe way too big to be useful for a port little mini-figure patient.
The ambulance features opening rear door, detailed interior and removable stretcher. You can remove the roof to play and look inside the ambulance. This is a big ambulance at 6″+ (17cm) long. This is the only LEGO ambulance I have ever seen where you can have the paramedic and the patient fit inside at the same time.
This set cost $19.99 when it was introduced. It was retired in 2012 not tool long after it was first introduced. Therefore, a set new in box is rather a rare find. Of the NSIB sets that were found, the average price is around $102 with the highest price found around $148. This is about a 400% increase in price. Therefore, set 4431 seems to have been a great investment.
