大型プレス材を有効に用い、少ない部品点数で組み上げられた軽量モノコックボディのデザインは、サイズや横置きリーフスプリング使用の前輪サスペンション構造ともども、1962年に開発されたドイツの小型大衆車オペル・カデット（そのバッジエンジニアリング版にあたるイギリスのボクスホール・ヴィーヴァを含む）の影響が非常に強いものであった。

The front crossmember (steering, suspension and engine mounting) assembly from the HA [GM's Vauxhall HA twin of GM's Opel Kadett] became a very popular item for DIY hot rod builders in the UK, due to its simple self-contained mechanics, similar to older designs such as those from the 1930s, and ability to accommodate much larger engines within its span. The assembly featured a double wishbone/vertical telescopic dampers suspension design in combination with a transverse leaf spring attached to the front cross member at its centre position and the entire unit could be removed and adapted to another vehicle as a complete unit.
