The only car to have had a speaking role in a muppets movie and to appear in two of the movies.
This is the actual Muppets Morgan pedal car unique registration number LG 10 as used in Carwash and Bear on Patrol as per youtube clips referenced below. This car was purchased in Harrods for the Muppets productions with the unique plate LG 10.
You can see the registration LG 10 on the Carwash Video. Hamilton Brookes and Co sold perhaps 100 of these pedal cars all with a unique registration plate mainly through Harrods. LG 10 has recently been the subject of a very light professional restoration including lights, horn and battery system and is in full working order.
