It is possible to fit special earthing strips to the back fender (bumper) of your car which touch the road: they discharge the static electricity your car accumulates, so theoretically preventing you from experiencing an electric shock when you leave your car.
They are sometimes called "anti-static strips".

Thank you so much mate! [:D]

One of the reasons the shock is so annoying is that you tend to touch things with your fingertips - there are lots of nerves here and so the sensation is strong. Make sure that the first metal object that you touch after getting out of your car is touched with your knuckle !

wow, good thinking...I guess touching the door with my knuckle first would be much more efficient than struggling to close the car door with my feet all the time!

why would the car be getting charged in the first place? i know you can get static build up from sandstorms is that it?

I believe the static charge is generated by the flow of (dry) air over the vechicle.

not a problem ive ever had but i livr in scotland.....no dry air

It's also possible that the charge is being built up between your clothes and the fabric of the car seat, especially if there's a rubber mat in the footwell, and/or you're wearing rubber soled shoes. Your body can accumulate a sufficient charge just due to you moving around in the seat while sitting inside the car, and which can then earth when you touch any conductive parts of the car. You can get various seat covers to address this.

I think Lee is correct. You can often avoid the problem if you discharge yourself through a key or a coin held by your fingers. The spark will them jump between the coin and the metal frame of the car, but you won't feel a thing.

This has some plausibility to it.
Dave, it's a lot more than "plausible". It's extrememly practical and proven. I used it for many years when I lived in Phoenix.
