Or remove the switch alltogether and manually turn off the motor when its in the right place... I can do that with my mini
But seriously it does look pretty bad, I saw a car yesterday that had all this fake sponsorship all over it, and the fake stick on alloy fuel cap... Gotta love the chrome exhaust tips, and I even saw a spoiler that was fitted backwards once
Some people have no idea, for example fitting a big spoiler to the back of a front wheel drive car!!! all that does is unloads the front wheels and increases drag and understeer

makes me smile though, so I guess its achieving something
The joy of owning a FIAT is to try and make it look like its a typical slow FIAT, right up until its disappearing ahead into the distance

So dont fit spoiler or stupid body kits (as Jerremy Clarkson says, it makes it look like it crashed into a china shop and everything stuck to it

)
