With an Ibex, you'll need to get hold of a complete defender bulkhead, to strip off the pedals, column dash and loom etc.
Obviously I'm biased
But advantages of an Ibex over a Tomcat etc
* Decent doors, and therefore the option of a warm dry cab
* Option of station wagon/king cab
* Awesome build quality
* Cheap and easy to replace GRP wheelarches, all the rest is ali/galv
* Will last a lifetime
* Centre winch is pretty cool and useful on challenges
* You get a new chassis
Tomcat would be lighter, and has a ARC spec cage, whereas the Ibex has a spaceframe that the ARC can't get their head around
Tomcat build quality.... I'm sure V8camel will be along in a minute
