Brian is definitely right
All Beetle Kits, wich are available are NOT matching the "1302"-Beetle (71-72 Super Beetle) they used in the Film! If you want to make it correct, choose the New Revell Beetle for the Rear, interior, sidewalls, windshield. Use the Italeri / Aoshima Superbeetle 1303 for the front (Suspension) trunk area - BUT the flat windschield needed from the Beetle Limousine. The Italeri / Aoshima Kit has the fat bumpers to attach.
