I spoke to Ainsty Andy & Dags ages ago about possible buggy conversions. As (thanks to Andy) I had a few spares, I decided to give it a go and after a bit of playing around with the bits box came up with (stole!) the idea for a global recovery vehicle:
I modified the Ainsty driver by removing some of the sculpted detail (arm badges etc). I added a (ProCreate) cap and sash, each with appropriate badges (apologies for the poor photo), and rounded off the collar:

The buggy was assembled as normal, but with the lights at the rear, as the front would be obscurred by the dozer blade. I then added various bits of plastic card, tube & items from the bits box. The roll-cage is a cut-down Westwind Victorian railing.

The buggy, driver, roll-cage & dozer were all kept seperate to aid painting:

All loosely fitted together, waiting for the driver:

The driver was painted (Really pleased with him):

Finally the roll-cage is added:

I'm now tempted to create more.....
