FFS, Whatever. That's right Robbo you'd know better

The rally cars were special builds and they weren't built solely for HDT either. Just like any other competion vehicle. WTF would you need to beef up a support vehicle when all you needed was available out of stock - like an Ambulance pack HZ van with an outback pack applied What were they going to beef up on them?

Plus it is well known at least one of the vans was a standard secondhand car. And it survived fine.
