Well........this is not a 'one piece chassis, 3 part interior and a body' kit These snappers will have multi part chassis, engine and pretty complete roll cage. True.....some parts may be 'grouped' and some simplified.......but the label Revell has started 'Snap Tite MAX' should tell you they are not just aimed at kids. If these are as good as promised I'll build these over the 'glue' version.......stock cars are just bodies after 3 or 4 builds.
