Come and get rid of your road rage

For R5 you can get rid of your road rage. Now that sounds like a bargin. I saw this smashed up taxi in the middle of a soccer field in a built up area. That is a little strange.

The field was behind a sturdy fence, so it could not have just been left there. The writing reads:

3 shots for R5
Come and get rid of your road rage

I assume that the enterprising owner was allowing you to take three shots at his smashed up taxi (with a gun?) for R5. The field is just behind the Sanbel Building in Belville. Can you shed any light on it?

Update (16 May 2011), today I drive past and they are gone. The plot thickens…
