Tantalisingly, you will need to wait until the very final step before fitting these maximum-grip tyres, but be prepared to be continually drawn to them throughout the construction. And LEGO couldn't ignore the ever-present commercial world of Formula One-stickers have been provided for all the main Williams sponsors, includng HP, Allianz, Castrol, BMW and Michelin to make sure that your final masterpiece bears the logos of all its financial contributors. The LEGO Williams F1 arrives with a 126-page pictorial manual (no language at all) that is simple and straightforward. Given the complexity of the final car this is in itself a significant feat. The box itself is also covered with illustrations of the car, seen from different angles or showing specific details of its construction. It helps to validate your work in progress as well as giving the sensation that you work out of a secretive F1 assembly garage, preparing for the next race. The final assembled masterpiece is a beautiful 65 cm long and makes a great collection piece to display in a bedroom or office. This Williams F1 car will take approximately 24 hours to build and although it is entirely possible to stop and start, do be aware of the strangely addictive nature of this serious LEGO kit. The LEGO Williams F1 is best enjoyed by adults and children aged at least 11 years. This is a serious toy offering maximum pleasure for big kids. -Hugo Rossignol.
