the last thing i did for the car is add a point constraint to make the whole car move. 

and i did the same for the rear

for the lights i added a driven and driven key to turn the lights on and off by typing in the channel box in light On Off , on or off

i also added side to side suspension by putting a orient constraint. 

i then rigged the boot of the car by adding a orient constraint

and i did the same for the back

after the doors i add suspension to the front i did this by adding an expression to the group

after the bonnet i added another orient constraint to the doors to male them open for the doors i think my placement for the controller works very well because i feel it is very obvious and in a good place for animating purposes

i then moved onto the bonnet of the car which again was done by adding a orient constraint 

then for the front wheels i added steering to the car again this was done by adding a orient constraint  

then in this image i used suspension to the wheel to do this i added a control and put a point constraint  

The first thing i did when i was rigging my car was rig the wheels in this image i added a orient
