LEGO 646-2 Mobile Site Office is a LEGOLAND Vehicle / Traffic set released in 1971, containing 51 pieces. The set builds a blue pickup-style truck with a yellow flatbed, designed to tow a red mobile construction site office trailer. The trailer features a printed “Site Office” brick, small window elements, and a detachable design for display or play. Typical of early 1970s LEGOLAND vehicles, both the truck and trailer are built at a pre-minifigure scale using simple brick-based techniques rather than molded vehicle bases. Based on current trends, this set could be valued near $179 within the next year.
Mobile Site Office is a relatively rare vintage set. We have not seen set 646-2 for sale in primary or secondary markets for over 6 months. Its market value is likely somewhat higher than our estimate. The last brand new Mobile Site Office was sold on eBay.

About LEGOLAND Vehicle

The LEGOLAND Vehicle theme is a subset of the broader LEGOLAND line from the 1970s and 1980s. This specific theme concentrated on various vehicles, from cars and trucks to boats and airplanes. Using a more simplistic design approach characteristic of that era, the sets aimed to recreate everyday transportation modes.

Vehicle consists of 47 sets that ran from 1970 to 1977. As of today, 611 Police Car is the most valuable Vehicle set with an estimated new/factory sealed value of $705.
