Blender 3D car physics/game (BGE)

A car game I made in the Blender Game Engine using a Lamborghini Gallardo model I made a while ago. Runs smoothly at 120 fps. you&probably wondering what a Lamborghini is doing in this place, and so am I. I know the menus need work, but I couldn&find any information on linking the score between the game and the end menu, or a way to be able to set the time in the start menu.
